 By  Daily Mail UK, 6 February 2014
Philip Seymour Hoffman had close  to 50 bags of heroin inside his $10,000 a month Manhattan apartment when  he died and more than 20 used syringes according to law enforcement  sources - who have now launched a city-wide search to catch his drug  dealer.
The shocking  new details reveal that the Oscar winner - who was found dead on Sunday  on the bathroom floor with a needle sticking out of his arm - had a drug  problem that had escalated far and above what had previously been  acknowledged.
And the stark  reality of Hoffman's struggle with relapse into addiction were  apparently confirmed by his estranged partner, Mimi O'Donnell - who told  police that the actor appeared high when she saw him the day before he  died.
Indeed, the Oscar  winning actor was pictured in an Atlanta bar on January 30 drinking,  smoking and repeatedly running in and out of the restroom.
     
 
     
Passed out: Philip Seymour Hoffman is pictured unconscious on his New York bound flight from Atlanta after  spending the afternoon drinking before he boarded and (right) being  driven away from the flight by an airport cart on landing in the Big  Apple
The actor was seen by a diner  in a restaurant next door to the Hyatt in downtown Atlanta who said the  46-year-old appeared, 'sketchy.'
He  apparently was with a woman at the bar and made 'multiple trips' to the  bathroom - which alerted the fellow patron's attention.
Apparently Hoffman appeared intoxicated and was later seen at the airport, where he was described as 'drunk and disheveled'.
Pictures  taken on-board his flight and obtained by TMZ reveal the Hunger Games  star passed out almost immediately after his drinking session in the  downtown Atlanta bar.
According  to the passenger who took the pictures, Hoffman was out like a light  almost as he took his seat for the New York bound flight on Thursday  last week.
Later, the  Oscar winning actor came to and was described as 'groggy and disheveled'  and as soon as the flight touched down he was put on an airport cart  and driven away.

 Distraught: Philip Seymour Hoffman's assistant,  Isabelle Wing Davies enters the building where his ex-partner Mimi  O'Donnell lives with their children the day after the actor's tragic  death 
O'Donnell told  NYPD that she last saw the actor at 2pm on Saturday on the street near  to the West Village apartment he was living in.
She  told investigators that he appeared to be under the influence of drugs  and when she spoke to him again at around 8 pm on Saturday - he also  sounded high.
On Monday,  the NYPD announced a massive citywide search to find the drug dealer or  dealers who sold heroin to Philip Seymour Hoffman.
'An  internal email went out to all supervisors asking if anyone has had any  experience with those brand names of drugs,' a law enforcement source  said
'They’re going to try to find the source.'
And  in a touching gesture Australian actress Cate Blanchett appeared teary  eyed as she arrived at the apartment Hoffman once shared with O'Donnell -  just a block and-a-half from the apartment he was found dead in.
Carrying  bags, including a telescope - presumably for Hoffman’s children,  Cooper, 10, Tallulah, 7 and Willa, 5, the Oscar winner emerged from a  black Cadillac and with the help of an assistant.
Blanchett declined comment.  
Doctor: Hoffman's addictions were life-long disease
                              
               
           
                                 
     
 Tragic: The body of Philip Seymour Hoffman was  removed from his apartment building just before 7 p.m. Sunday after he  died on Sunday
    
 Friends: Philip Seymour Hoffman was reportedly  found dead on Sunday morning by his friend David Bar Katz (center) who  is pictured with another friend George Liberatto in 2008
 
Blanchett, who worked with  Hoffman on the 1999 movie, The Talented Mr Ripley is also up for another  Oscar this year for her part in the Woody Allen movie, Blue Jasmine.
This comes as a report claimed that Hoffman's lost his family because of his heroin addiction.
Refuting  all suggestions that the 46-year-old had been kicked out by his partner  of 14-years because of an affair - friends confirmed that Hoffman had  been asked to leave for the sake of his three children as he was  battling a huge drug habit.
'It  was known that he was struggling to stay sober, and girlfriend Mimi  O’Donnell had given him some tough love and told him he needed some time  away from the kids and to get straight again,’ a Hollywood source said.
'They  were living separate lives,’ a law-enforcement source said of Hoffman  and O’Donnell. He was living over here, she was living over there. You  do the math.’ 
Broadway  announced Monday that it would dim its lights for one minute at 7:45 pm  on Wednesday in memory of the celebrated stage and screen actor.
Charlotte St Martin, executive director of the Broadway League, described Hoffman as a 'true artist who loved theater.
'We'll  always be grateful for his boundless and profound talent that he shared  with us on the Broadway stage. Our thoughts go out to his family,  friends, and fans,' she added.
So far officers have found no evidence of a struggle inside the apartment and it was here his body was found  Sunday morning by close friend and playwright David Bar Katz and British assistant Isabella Wing-Davey, who had  been asked to check up on him by Miss O'Donnell. 
According  to neighbors, O'Donnell was with her children when she rushed to see  Hoffman after receiving the terrible news from Wing-Davey and Katz.
Hoffman had apparently arranged to meet them at a nearby playground just a block and a half away.

However  when she was told that he had been discovered slumped on the bathroom  floor she put her kids in her car, rushed to the West Village apartment  and left her children in the running vehicle as she dashed inside,  shouting, 'I have to see him!'
The medical examiner is to perform an autopsy today to determine the cause of death - with a drugs overdose strongly suspected.
Indeed,  authorities searching the fourth floor apartment recovered 49  containers of heroin, almost two dozen used syringes as well as  anti-anxiety prescriptions that Hoffman didn't appear to have a script  for.
 
 According to police sources,  Hoffman had in his possession, the blood-pressure medication clonidine  hydrochloride; the addiction-treatment drug buprenorphine; Vyvanse, a  drug used to treat attention-deficit (hyperactivity) disorder;  hydroxyzine, which can be used to treat anxiety; and methocarbamol, a  muscle relaxer.
Police also discovered several other bags containing white powder.
Wing-Davey,  who is thought to be 28, holds a BA from Cambridge University in  History, and is currently a thesis student in NYU’s Tisch School of the  Arts Graduate Film Program.

'They were  friends, very good friends,' said Meg Gibson, who worked with Hoffman  and Wing-Davey on Candlesticks - a short film that listed Hoffman as  assistant director.
DID PHILIP SEYMOUR HOFFMAN BUY HUGE STASH OF DEADLY TAINTED HEROIN?
 Oscar  winner Philip Seymour Hoffman was discovered dead on the bathroom floor  of his 4th floor apartment literally surrounded by heroin and its  attached paraphernalia.
Some of the empty heroin envelopes were branded with an Ace of Spades log - other with an Ace of Hearts.
The  Ace of Spades heroin has been spreading across the country - on July 7,  2011 12 people in Wichita, Kansas, were indicted on heroin trafficking  charges - that centered on selling the drugs into New York City.
The  majority of the trafficking was to Brooklyn and Queens - from where it  would be distributed to Manhattan and into Long Island.
Ace  of Spades heroin reared its head again on January 16 when authorities  arrested Kendall Sistrunk, 49, with transporting heroin from New York to  Stamford, Connecticut.
'Police  found 44 bags of heroin with an Ace of Spades brand with a street value  of about $900,' according to Captain Richard Conklin, head of  Stamford’s Narcotics and Organized Crime Squad.
Indeed,  it is suspected that the Ace of Spades brand is responsible for close  to 100 deaths from New Hampshire to Washington State - including 37 in  Maryland since September. 
 Gibson said that Hoffman was close  friends with Wing-Davey’s father, Mark Wing-Davey, who chairs the  graduate acting department at Tisch - and who also graduated from  Cambridge University in 1970.
A  close friend of tragic Oscar winner Philip Seymour Hoffman has told how  he was ‘mentoring’ his assistant Isabella Wing-Davey before his death –  and insisted there had not been any romantic relationship between the  pair.
Actress Meg Gibson,  who worked with the pair on the short film Candlesticks stressed to  MailOnline today: ‘They was nothing romantic between them at all,  absolutely not.
Grief-stricken  Bella found the star’s body at his rented Greenwich Village apartment  on Sunday morning, alongside playwright David Katz.
Only two weeks ago she had accompanied the actor to the Sundance Film Festival and was pictured strolling with him.
‘Bella’s  father Mark worked with Phil at the Public Theater and Bella has known  Phil since she was a child. Phil brought her into his company to be his  development person when she was finishing her graduate work at Tisch  School of the Arts, ‘ Meg said.
‘She’s highly skilled and highly talented, she won the Director’s award at Tisch last year.
‘Phil didn’t tolerate fools and he was a mentor for Bella, she was learning her way in the business as a family friend.’
Meg said Philip’s death had come as a ‘terrible shock’.
Having  known the actor for decades, the actress said it was shocking that his  drug abuse had reared its head again after 23 years of sobriety, adding:  ‘He was clean for 23 years and I’ve had many, many a dinner with him  where he didn’t have anything to drink.

‘There are lots of people we’re  all aware of who have had abuse issues and it’s just shocking and  terrifying that it can rear its head.’
Meg appeared in Candlesticks, which was directed by Bella and listed Philip as assistant director.
When  asked about his recent split from long-term girlfriend Mimi O’Donnell,  with whom Phil has three young children, Meg said: ‘Whatever was going  on they kept it very quiet, all I knew is that Phil was a devoted father  and was especially close to his son. He saw the children every day.’
Describing  Mimi as a ‘fantastic costume designer and wonderful mother’, Meg told  how Mimi had run the Labryinth Theater in New York when Philip took a  leave of absence, saying: ‘She’s a fantastic person.’
Investigators found eight empty bags stamped with 'Ace of Spades' and 'Ace of  Hearts' inside the actor's Manhattan apartment, according to  officials. 
They usually contain a lethal mix of heroin laced with fentanyl - an opiate used to soothe the pain of cancer patients.
The card-inspired brand names are among  hundreds of stamps used by drug distribution crews to mark products,  but they haven't been seen in New York since 2008
Their lethal contents - also known as 'Bud Ice', 'Income tax' and 'Theraflu' - have been linked to more than 100  deaths in America - with more three dozen deaths in Maryland since September. 
Meanwhile,  there have been almost 20 related deaths in Pennsylvania in this month  alone - with officials estimating a further 22 people dying of  heroin-fentanyl overdoses in Rhode Island during the first two weeks of  this year
Now, police are investigating whether the Oscar award-winning actor may have died after  injecting the lethal concoction, according to a source.

Fox reported a man has come forward claiming they he saw Hoffman buying drugs earlier in the evening. 
The  passerby claims he saw a 'very sweaty' Hoffman withdrawing a large sum  of money from an ATM by his home before handing it over to two men  wearing messenger bags. 
The man reportedly added Hoffman looked 'like s**t'. 
Police are now seeking surveillance videos from the bank.

 It  comes as a haunting last photo has captured 46-year-old Hoffman's  torment following his split from his long-term girlfriend, Mimi  O'Donnell, in recent months.
PHILIP SEYMOUR HOFFMAN'S BRILLIANT CAREER
    
   
Hoffman won an Oscar for his  portrayal of the witty, theatrical Truman Capote in Capote in 2006 and  received four Academy Awards nominations and several nominations for  theater awards, including three Tonys. 
He  was equally acclaimed and productive, often appearing in at least two  to three films a year, while managing an active life in the theater. He  had been thriving for more than 20 years and no one doubted that a long,  compelling run awaited him. 
With  a range and discipline more common among British performers than  Americans, Hoffman was convincing whether comic or dramatic, loathsome  or sympathetic, powerless or diabolical. 
In  one of his earliest movie roles, he played a spoiled prep school  student in Scent of a Woman in 1992. A breakthrough came for him as a  gay member of a porno film crew in Boogie Nights, one of several movies  directed by Paul Thomas Anderson that Hoffman would eventually appear  in. He played comic, off-kilter characters in Along Came Polly and The  Big Lebowski. 
He  bantered unforgettably with Laura Linney as squabbling siblings in The  Savages. He was grumpy and idealistic as rock critic Lester Bangs in  Almost Famous. He was grumpy and cynical as baseball manager Art Howe in  Moneyball. 
In  The Master, he was nominated for a 2013 Academy Award for best  supporting actor for his role as the charismatic, controlling leader of a  religious movement. 
The film, partly inspired by the life of Scientology founder L. Ron Hubbard, reunited the actor with Anderson. 
He  also received a 2009 supporting nomination for Doubt, as a priest who  comes under suspicion because of his relationship with a boy, and a best  supporting actor nomination for Charlie Wilson's War, as a CIA officer.  
Many  younger moviegoers know him as the scheming Plutarch Heavensbee in The  Hunger Games: Catching Fire and he was reprising that role in the  two-part sequel, The Hunger Games: Mockingjay, for which his work was  mostly completed. The films are scheduled for November 2014 and November  2015 releases. 
On  Broadway, he took on some of the stage's most ambitious parts - Willy  Loman in Death of a Salesman, Jamie in Long Day's Journey Into Night and  both leads in True West. All three performances were Tony nominated. 
in  2013 Hoffman crossed to the other side of the footlights to direct Bob  Glaudini's A Family for All Occasions for the Labyrinth Theatre Company,  where he formerly served as co-artistic director. Hoffman has also  directed Jesus Hopped the A Train and Our Lady of 121st Street for the  company and received Drama Desk Award nominations for both productions.
Hoffman's  last public appearance was at the Sundance Film Festival last month,  where two films he starred in were premieried - A Most Wanted Man and In  God's Pocket.
 Hoffman,  who has three elementary-age children with the costume designer, also  46, began renting a $10,000-a-month apartment in Bethune Street in  Manhattan's Greenwich Village in October.
The actor's estranged  partner was later seen weeping as she entered the property.
On Sunday  afternoon, a New York Police Department source told MailOnline: 'It is  my understanding that Mr Hoffman and his girlfriend were separated.'
Mr  Hoffman's last public appearance was at the 2014 Sundance Film Festival  in January, where he was promoting his movie, 'God's Pocket,' and also  'A Most Wanted Man.'
He appeared 'slightly disheveled and pasty,' 
He had a five o'clock shadow, pale complexion and watery eyes, appearing altogether worn out.
He  kept some press commitments, posing on the carpet with his Most Wanted  co-stars Rachel McAdams and Willem Dafoe, dressed in baggy clothes.
However,  he declined a number of interviews, with his representative telling  reporters the actor 'needed a minute and didn't feel like coming down  yet.'
Miss O'Donnell, Mr  Hoffman's partner of 14 years, contacted Mr Katz after the actor failed  to collect son Cooper, 10, and daughters Tallulah, 7, and Willa, 5, Sunday morning. 
Mr Katz then, with WIng-Davey, went to check on the actor. 
Wing-Davey  has long had a close relationship with the star after meeting him  through her actor father Mark Wing-Davey. Her cell phone has a recorded  message asking callers to leave a message for Bella Wing-Davey and Phil.  
It was Wing-Davey, a  film-maker and writer, who called 911 to report the body. She was then  photographed outside the apartment clutching her tan scarf to her face  as she spoke to detectives with Mr Katz. 
The pair found Mr Hoffman in his underwear on a bathroom floor at  apartment 4D, 35 Bethune Street around 11:30 a.m. Allegedly, he had a syringe still in his  arm.
Miss  O'Donnell was later said to have arrived at the scene but was banned  by cops from entering the bathroom, sources said. 
After remaining in the  apartment all day, the actor's body was finally taken from his home just before 7 p.m.
It  later emerged that the night before he was found dead, Mr Hoffman  enjoyed a cheeseburger with friends at one of his favorite restaurants.
The actor dined at West Village restaurant Automatic Slims  with two other men from around 7 p.m. A witness told the magazine he was  drinking cranberry and soda and seemed 'totally fine.' 
'The  friends he was with seemed like industry people. He had a cheeseburger.  He was low-key and friendly and none of them looked like they were  looking to party,' the witness said. 
'He  comes in occasionally and just keeps a low profile. He hardly ever  drinks. Such a nice guy and very unexpected to hear this news.'
On  Saturday, employees from one of his favorite places to take his kids -  the Chocolate Bar on Eighth Avenue - reported seeing him looking 'really  happy'. 
'Everyone seems pretty shaken up,' said Kate St. Cyr, 24, the assistant manager said
'We just saw him yesterday, he was fine,' she added. 'He's been in a great mood, really happy.' 
She  described Hoffman as a 'really sweet man and dad' who would often take  his children to the store for ice cream in the summer. 
The  actor had a specially close bond to his son Cooper who he regularly  played weekend basketball with and was often photographed with at Knicks  games in Madison Square Garden.  
'He  seemed to have a really great relationship with his kids,' St. Cyr went  on. 'That's, I think, what's upsetting most of us. We feel really sad  for his kids.'

The neighbor added Hoffman looked 'grey' and 'not well' before he joined friends for his low-key dinner.
'A  Most Wanted Man' director Anton Corbijn said he was shocked to hear  about the death of the actor who just two weeks ago seemed 'in a good  place.'
'We spent some time together only  [two] weeks ago and he seemed in a good place despite some issues he had  to deal with,' Mr Corbijn told the Post. 
'He  was not only the most gifted actor I ever worked with (and judging by  the legacy he leaves behind I am certain I share this with most if not  all directors who were fortunate enough to work with him), he had also  become an incredibly inspiring and supportive friend. 
'I am so terribly  sad as I find it impossible to comprehend what happened today and to  collect my thoughts properly.'
He added: 'I have to think about Mimi  and the children and [I] wish them much strength coping with the loss of  this truly great man as a father and partner.'
And  today, Seymour Hoffman's college friend and former 3rd Rock From The  Sun star, Kristen Johnson posted onto Twitter her tribute, where she  acknowledged he was an addict.
'Thank  you for all your kind words about Phil. Sadly, after being sober for  years & years, he relapsed & has been grappling with his  addiction for last few years. 
'I wish I could say I was shocked, but all I feel is a mixture of terrible grief, sad resignation & a powerful rage.
'Many,  many people die from this disease. Like them, Phil didn't want to die.  He fought hard to get clean. He had a family he loved, many friends who  adored him & a career he was proud of.
'But addiction doesn't care about that.'
Hoffman moved into his new West Village apartment around Christmas time, MailOnline can reveal.
Neighbors  said that it was two months at most since he had begun renting the  $10,000 a month luxury apartment in New York's West Village.
The timing of his departure gives new insight into the traumatic separation from his family that the actor was going through.

The superintendent of the building, who declined to give his name, said that Hoffman had been there two months.
A man in his 60s who said he was the dog walker however said it was sooner, and six weeks at most.
He said: 'I'm in and out of that building 30 times a day and it has been a matter of weeks he's been here'.
Earlier, a neighbor at the $4.4 million apartment Mr Hoffman and Miss O'Donnell  owned together in Jane Street, less than three blocks away from his rental home,  described him as 'a troubled soul' to the New York Post.
The couple bought the three-bedroom, 2-1/2-bath apartment in 2008.
'He did not look well recently — like he was out of it,' the woman said. 'I think him and his woman friend were off and on.'
'He lived down here for a long time and was well liked, but everyone knew he had substance-abuse problems,' she added.

Just over a week ago, Mr Hoffman was spotted in the audience at the Broadway revival of 'Waiting for Godot.'
Mr  Hoffman won the best actor Academy Award for the 2005 film, Capote,  and has been hailed by the film industry as one of the finest actors of  his generation.
The Fairport, New York, native  reportedly told TMZ in May that he began taking heroin again after  23 years of being clean. He said he'd progressed from prescription pills to ultimately snorting heroin.

He claimed that he only used heroin  for a week before he realized he needed help and checked himself into a  detox facility on the East Coast.
He spent 10 days receiving treatment and credited a 'great group of friends and family' for helping. 
'I saw him last week, and he was clean  and sober, his old self,' Mr Katz, a screenwriter, said on Sunday. He said he called 911 after finding Mr Hoffman. 'I really thought  this chapter was over.'
Authorities confirmed that the last time the stage and film actor was last seen was around 8 p.m. on Saturday. 
The   Office of the Chief Medical Examiner is yet to determine the exact  cause of  death, but law enforcement sources revealed a drug overdose was to  blame. Officers found a charred spoon in the kitchen sink, police  sources told the New York Post.

A relative told The Post: 'We're just really devastated that this could happen.'
'There had always been a concern with the business he was in,' said Doris Barr, 76, whose son is married to Mr Hoffman's sister.
After Mr Katz called 911, emergency workers rushed to the scene  where Mr Hoffman was declared dead on arrival.
Just before 7 p.m., after CSU  investigators, wearing white plastic suits, spent the entire afternoon  and much of the evening going in and out of Mr Hoffman's apartment, the  crime scene van moved to make way for the medical examiners wagon to  pull up to the building.

Police flanked both sides of the van  all the way to the buildings entrance. After 10 somber minutes, a  stretcher was wheeled out carrying a figure covered in black plastic and  was loaded into the wagon before being quickly whisked away with  blaring horns and blinding blue and red lights.
Earlier, neighbors said the actor looked ill when they last  saw him.
'Just the  other day I saw him getting out of his mini cooper with his kids and his  wife I guess. He was in sweatpants and a beanie and he looked  disheveled,' said Olivia De Santis as more than 100 people gathered outside the actor's home.
The family of the actor issued a statement to the media in the aftermath of his death to thank everyone for their support.
'We are devastated by the loss of our  beloved Phil and appreciate the outpouring of love and support we have  received from everyone. This is a tragic and sudden loss and we ask that  you respect our privacy during this time of grieving. 
'Please keep Phil in your thoughts and prayers.'

In 2006, Mr Hoffman admitted his history of substance abuse after he graduated from NYU's drama school.
'It  was all that drugs and alcohol, yeah. It was anything I could get my  hands on…I liked it all,' he told 60 Minutes at the time.
Mr  Hoffman, who was no matinee idol figure with his tubby build and  scruffy blond hair, made his career mostly as a character actor. He was  nominated for Oscars four times in all -- best actor for Capote, which  he won, and best supporting actor in The Master, Doubt, and Charlie  Wilson's War.
In one of his earliest films, he played a spoiled prep school student in 'Scent of a Woman' in 1992. 
A breakthrough role came as a gay member of a porno film crew in  'Boogie Nights,' one of several movies directed by Paul Thomas Anderson  that he would eventually appear in.
He often played comic, slightly off-kilter roles in movies like 'Along Came Polly,' 'The Big Lebowski' and 'Almost Famous.' 
Just  weeks ago, Showtime announced Mr Hoffman would star in 'Happyish,' a  new comedy series about a middle-aged man's pursuit of happiness.
In  'The Master,' he was nominated for the 2013 Academy Award for best  supporting actor for his role as the charismatic leader of a religious  movement. 
The film, partly inspired by the life of Scientology founder L. Ron Hubbard, reunited the actor with Anderson.
He also received a 2009 supporting  nomination for 'Doubt,' in which he played a priest who comes under suspicion because of  his relationship with a boy. Meanwhile, in 'Charlie Wilson's War' he played a convincing CIA officer.
Mr. Hoffman appeared in more than 50 films in a career that spanned less than 25 years.
Born  in 1967, Mr Hoffman was interested in acting from an early age,  mesmerized at 12 by a local production of Arthur Miller's 'All My Sons.'  
He studied theater as  a teenager with the New York State Summer School of the Arts and the  Circle in the Square Theatre. He then majored in drama at New York  University's Tisch School of the Arts.

HOLLYWOOD PAYS TRIBUTE
Gwyneth Paltrow 
'Philip was a true genius.' 
Sir Ian McKellen
'He  was without doubt one of the most accomplished screen actors of our  time, with so many more performances waiting to enchant us with. His  work on film survives his death, the only consolation in our grief and  regret.'
George Clooney (speaking to The Hollywood Reporter)
'There are no words. It's just terrible.'
Tom Hanks
 'This is a horrible day for those who worked with Philip. He was a giant talent. Our hearts are open for his family.'

'I  feel so fortunate to have known and worked with the extraordinary  Philip Seymour Hoffman, and am deeply saddened by his passing.'

'I'm  so shocked, and so sad hearing of Philip Seymour Hoffman's death. I  enjoyed playing with him on the Big Lebowski. He was such a wonderful  guy, and so damn talented, a real treasure. My thoughts and prayers are  with his family.'
Aaron Paul
'We lost one of the greats today. Philip Seymour Hoffman RIP my friend. You will be missed always and forever.'
Sam Claflin
'PSH  - I am genuinely shocked, saddened and speechless. A truly wonderful  man, with a magical touch. My hero. Thoughts are with his family.'
Clifton Collins
'PSH was beyond magical in his skills.'
Ellen DeGeneres
'Philip  Seymour Hoffman was a brilliant, talented man. The news this morning is  shocking and sad. My heart goes out to his loved ones.'
 Trained  in the theater, with a versatility and discipline more common among  British performers than Americans, he was a character actor who could  take on any role, large or small, loathsome or sympathetic.
On the stage, he performed in revivals  of 'True West,' ''Long Day's Journey Into Night' and 'The Seagull,' a  summer production that also featured Meryl Streep and Kevin Kline.
In  2012, he was more than equal to one of the great roles in American  theater — Willy Loman in 'Death of a Salesman,' a performance praised as  'heartbreaking' by Associated Press theater critic Mark Kennedy.
'Hoffman is only 44, but he  nevertheless sags in his brokenness like a man closer to retirement age,  lugging about his sample cases filled with his self-denial and  disillusionment,' Mr Kennedy wrote. 
'His  fraying connection to reality is pronounced in this production, with  Hoffman quick to anger and a hard edge emerging from his babbling.'
He  also directed and acted in Off Broadway shows for the Labyrinth Theater  Company, a New York troupe, which he served for a time as artistic  director.
In 2003, he played James Tyrone, a doomed addict in 'Long Day's Journey Into Night.'
'The theater was very difficult for him,' the play's director Robert Fallstold the New York Times Sunday night. 
'It  cost him; there was an emotional cost to the work, having to do it for  eight performances a week, and having to rehearse. In "Long Day's  Journey," a role about an addict who would be dead in a number of years,  who was filled with self-loathing, certainly Phil had access to those  emotions. 
'But I'm not  talking about a method actor. He just brought every fiber of his being  to the stage. He was there — with his depth of feeling, depth of  humanity — and no other actor I've ever worked with ever brought it like  that, not at that level.'
The  actor was known for the enormous respect he commanded from his peers  says director Shane Salerno who produced his documentary, Salinger, with  the help of Mr Hoffman.
'To be honest, we were having trouble getting big names to participate,' said Mr Salerno.
'But  when he agreed to do it, other people began getting on board. Once Phil  signed up, it was like we had a seal of authenticity,' Salerno said
'The  interviews he gave were as good as the Yale professors we spoke with.  You can't imagine how intellectual he was about film, stage, literature.  He was as smart as they come.'
