Enchanted (2007)

Giselle's hand-drawn fairy-tale kingdom plays in 1.85:1. When she tumbles into modern Manhattan and the movie becomes live action, the frame stretches to anamorphic 2.35:1, so the real world literally looks bigger and less tidy than the one she left. It doubles as a neat in-joke on the difference between classic animated features and live-action blockbusters, and it gives a breezy musical comedy a bit of formal wit that grown-ups will catch even if the kids don't.
