Her role in Willy Wonka and the Chcolate Factory would clearly be her most popular role due to the way the film has remained relevant over the decades. It really is a fantastic film. When you watch it as a kid it’s bright and fun and silly. Then, when you watch it again when you get older, you realize just how dark and twisted the humor really is. This ability to provide something that appeals to a wide audience, and actually change over time, is why the film has remained popular to this day.
