I KNEW IT WAS YOU: This exclusive presentation is a portrait of actor John Cazale, whose big-screen career encompassed just five movies - five of the greatest films of his generation - before his death from cancer at age 42 in 1978. Each earned a Best Picture OscarĀ® nomination and teamed him with some of the leading actors and directors of the 20th century. Interspersed with clips from "The Godfather," "The Godfather: Part II," "The Conversation," "Dog Day Afternoon" and "The Deer Hunter" are rarely seen photos and home video, as well as candid interviews with a pantheon of Hollywood royalty, including Al Pacino, Gene Hackman, Robert De Niro, Richard Dreyfuss, Meryl Streep and Sidney Lumet. Directed by Richard Shepard; produced by Brett Ratner, Stacey Reiss and Richard Shepard. Debuts June 1.
