Over at the Garden of Forking Paths, there's a post about movies that touch on themes in action theory.

I thought about the possibility of teaching a philosophy 101 class using just movies. Let's say you were planning the curriculum for such a class. Which movies do you think would best illustrate basic themes and subthemes in ethics, metaphysics and epistemology?

You don't have to provide a complete list. Any suggestion to get the ball rolling will be fine.
