John Cazale was in only five films – The Godfather, The Conversation, The Godfather: Part II, Dog Day Afternoon and The Deer Hunter – each was nominated for Best Picture. Yet today most people don't even know his name. I KNEW IT WAS YOU is a fresh tour through movies that defined a generation.
Unfortunately the movie I Knew It Was You: Rediscovering John Cazale is not yet available on HBO Max.
