Pat Hingle
This is one of my all time favorite movies. Natalie Wood and Warren Beatty were fantastic, but I feel like Pat Hingle stole every scene he was in. He was larger than life, kind of looks and sounds like what I imagine Teddy Roosevelt to be like. You could almost see his point of view, how he wanted the best for his son, even though he clearly went too far keeping his son away from Deanie and the sort of life that Bud really wanted. I know Hingle had other movie roles, after watching this I'm surprised he wasn't in more things. I know 1961 year had tough competition for Best Supporting Actor, but I think Hingle should have been nominated for an Oscar for this.
