Other noteworthy films included "Moneyball," "The Savages," "Cold Mountain" and "Scent of a Woman," one of his earliest films, which garnered its star, Al Pacino, an Oscar.

 Lionsgate, the studio behind "The Hunger Games," called Hoffman "one of the most gifted actors of our generation."

 "We're very fortunate that he graced our 'Hunger Games' family. Losing him in his prime is a tragedy, and we send our deepest condolences to Philip's family," the studio said in a statement.

"The Hunger Games: Catching Fire" grossed $860 million worldwide and stands out as the most commercially successful movie of his career. He had filmed scenes for two sequels in the blockbuster franchise, which are still in production.

His work was "substantially complete" on "The Hunger Games: Mockingjay — Part I" and he had seven shooting days remaining on "Mockingjay — Part 2," according to a person close to the films who was not authorized to talk to the media. The actor's death will not affect the films' scheduled release in November 2014 and 2015, the person said.

Hoffman also was scheduled to direct the Prohibition-era drama "Ezekiel Moss" starring Amy Adams and Jake Gyllenhaal.

 Hoffman also frequently appeared on Broadway, earning Tony award nominations for his role as the main character Willy Loman in "Death of a Salesman," and for his parts in "Long Day's Journey Into Night" and "True West."

"If you missed him as Willy Loman, you missed a Willy Loman for all time," actor Steve Martin said on Twitter on Sunday.

 "This is a horrible day for those who worked ‎with Philip," Tom Hanks, who co-starred with him in "Charlie Wilson's War," said in a statement. "He was a giant talent. Our hearts are open for his family."

 Jeff Bridges wrote on Facebook he enjoyed acting alongside Hoffman in "The Big Lebowski," in which Hoffman played an overbearing, scheming heir. "He was such a wonderful guy, and so damn talented, a real treasure," Bridges wrote.

New York Mayor Bill de Blasio said via Twitter: "Saddened by Philip Seymour Hoffman's tragic and untimely passing. Today New York mourns the loss of one of stage and screen's greats."

 Showtime, the cable television network which had just ordered a 10-episode comedy, "Happyish," starring Hoffman and produced by his company, Cooper's Town Productions, mourned the loss of the talented actor.

 "Philip Seymour Hoffman was one of our generation's finest and most brilliant actors. He was also a gifted comedic talent. It was a great privilege and pleasure to work with him and we are all absolutely devastated by this sudden loss," it said.

 Hoffman appeared last month at the Sundance Film Festival in Utah for the premiere of "A Most Wanted Man," an espionage thriller based on the John le Carre novel in which he played German spy Gunther Bachmann.

 At the premiere, Hoffman told Reuters that he connected to Gunther's personality, a man driven by the shame of previous failure into an obsessive pursuit of capturing terrorists by any means necessary.

 "I think it'd be hard for anyone not to connect with the loneliness. He's pretty lonely, driven, obsessive guy, unforgiving of himself in a lot of ways. A lot of traits that a lot of people carry in one grade or another," Hoffman said.

"We spent some time together only two weeks ago and he seemed in a good place despite some issue he had to deal with," said Anton Corbijn, director of "A Most Wanted Man," without elaborating further.
