Willy Wonka and the Chocolate Factory

'Willy Wonka and the Chocolate Factory' is a 1971 children's fantasy musical film based on the Roald Dahl 1964 book 'Charlie and the Chocolate Factory'. The film is about a young poor boy Charlie Bucket and the resurface of famous chocolatier Willy Wonka, who's stashed five golden tickets in his chocolate Wonka bars throughout the world. The tickets' finders, including Charlie and four spoiled children, are allowed into his factory and given the chance to win a mysterious special prize.

One of the spoiled children, gum-chewing Violet Beauregarde, tries an experimental gum of Wonka's that inflates her body and turns her into an immobile human blueberry. In production, her actress Denise Nickerson wore two suits to simulate her sudden expansion. For the initial stage, a larger version of her normal outfit that was pleated and inflated with an air hose at the back, which can be seen in the full-screen version of the movie. For the full completed blueberry form, a big spherical ball composed of two halves of Styrofoam was used.
