'Willy Wonka' Behind-The-Scenes Secrets Revealed
"Willy Wonka & the Chocolate Factory" has been terrorizing kids for over 40 years (the boat scene still gives us nightmares). And while the classic 1971 movie has inspired quite a few theories about what's really happening on-screen, there was apparently a lot going on off-screen, too.

In the above video, WGN Morning News reveals some delicious tidbits about "Willy Wonka & the Chocolate Factory," including:

- Peter Ostrum, who played Charlie, went through puberty during the film. His voice is high when he wins the golden ticket and is noticeably lower in the bubble scene.

- Gene Wilder was memorably zany as Willy Wonka, but other candidates for the role included Peter Sellers and the members of Monty Python. (How funny would it have been for Wonka to tell Violet, "It's just a flesh wound"?)

- The Oompa Loompas were German and couldn't speak English.

- One of the Oompa Loompas was a woman! (Can you tell which one?)
