Gene Wilder's Willy Wonka was a frightening man. When he first appears, he is staggering painfully about on a cane; then he falls, turns it into a somersault and finishes with a melodramatic "Ta-dah!"

It couldn't be clearer. "You think you know who I am? You think you know what I want? Wrong. I'm lying to you." He is less a candy maker than the Satan of a chocolate-themed purgatory. Horrible things will happen to you there - unless you are both noble and incorruptible.

Johnny Depp's was a weirdo.
