The Moulin Rouge and Recursion

I particularly like films that are deeply self-referrential. The Moulin Rouge is one that does not get enough credit. The lines between levels of fiction blur in the film that is about a writer writing a story on his own experience writing a play about his love with the lead actress. The play itself is based on this love; it predicts his own experiences, and his motivations change the play during conception and execution. The constant camera tricks that suspend belief only further remind the audience that the story is fiction, creating all sorts of levels of self-awareness.

Movies like this need more credit, especially when it's done well.
