I like how Brooks honestly doesn't know why "The Producers" hit it so big, especially after he seemed washed up. I don't think anyone can explain it, and he's right, it just hit a nerve with people. Now there's a man with some understanding of reality and not delusions of grandeur and self-importance like many of today's pseudo-stars.
WHO could ever forget Dick Shawn's portrayal in "The Producers"? The flower-child Hitler.. lol
