Willy Wonka & The Chocolate Factory (1971)
The film for which Wilder is perhaps best globally known, Willy Wonka & The Chocolate Factory is based on the book by Roald Dahl. Wilder's creativity shines through in the idiosyncratic character of Willy Wonka-- he even came up with some signature phrases and moves, like the somersault Wonka does at the beginning of the film after exiting the chocolate factory.
