What a legend. Even if you only know him as Willy Wonka, you still love him. But he's had two other roles that are a couple of my all time favorite characters in movie history. Which would be Jim (aka The Waco Kid) from Blazing Saddles and Dr. Frankenstein in Young Frankenstein. Here are some clips for your viewing pleasure, along with some from Willy Wonka too.
RIP, my man. Legend.
