Philip Seymour Hoffman, who won the Oscar for best actor in 2006 for his portrayal of writer Truman Capote in "Capote" and created a gallery of other vivid characters, many of them slovenly and slightly dissipated comic figures, was found dead Sunday in his Greenwich Village apartment. He was 46.

The cause of death was not officially determined.

Hoffman — no matinee-idol figure with his tubby, lumpy build and limp blond hair — made his career mostly as a character actor, and was one of the most prolific in the business.
