Admired by actors and directors, adored by friends and lovers, yet unknown to most movie-goers, the venerable stage and screen actor John Cazale appeared in some of the most iconic films of the 1970's - Francis Ford Coppola's The Godfather, The Godfather: Part II and The Conversation, Sidney Lumet's Dog Day Afternoon and Michael Cimino's The Deer Hunter. The critically-lauded films collectively earned 40 Oscar nominations, including 14 for Cazale's co-stars, and raked in millions at the box office.
In 1978, just after wrapping The Deer Hunter, Cazale died tragically at age 42 and cinema was robbed of one its brightest. In I Knew It Was You, director Richard Shepard talks with Cazale's co-stars and friends, Al Pacino, Meryl Streep, Robert DeNiro, Francis Ford Coppola, Israel Horovitz, Phillip Seymor Hoffman, Steve Buscemi and Sam Rockwell, and paints a loving tribute to a talent taken too soon.
John Cazale's resume as a film actor isn't long, but it's distinguished. Cazale appeared in five feature films, and each one received an Academy Award nomination for Best Picture, while three of them -- The Godfather, The Godfather Part II and The Deer Hunter -- won the category. Al Pacino, who made three films with Cazale, considered him one his finest acting partners, and many film buffs cite Cazale as one of the best actors of his generation. But Cazale was thirty-seven years old before making his film debut after distinguishing himself in the New York theater community, and shortly after completing work on The Deer Hunter, cancer claimed his life in the spring of 1978. I Knew It Was You: Rediscovering John Cazale is a short documentary celebrating the life and art of Cazale, featuring clips from his memorable performances and interviews with friends, colleagues and fans, including Meryl Streep (who was also Cazale's wife), Al Pacino, Robert De Niro, Gene Hackman, Francis Ford Coppola, Sidney Lumet, Steve
Buscemi, Philip Seymour Hoffman and many others. I Knew It Was You was an official selection at the 2009 Sundance Film Festival.
