Willy Wonka And The Chocolate Factory (1971)

This freaky ’70s musical tinkers with the title and the plot (no squirrels, more Slugworth) to make a movie with an even darker aftertaste than Dahl’s original Charlie And The Chocolate

Factory novel – Dahl wasn’t a fan, despite the fact he co-wrote the screenplay. Gene Wilder turns the “odd” setting to maximum as the top-hatted confectioner, yet still looks comparatively normal next to Johnny Depp in Tim Burton’s more-faithful (and underrated) 2005 version.
