Written and directed by David Lynch. 2001.

Mulholland Dr. is a movie about Hollywood. As such, it fits snugly into a category of films that's one of my favorites: the dream factory dreaming of itself. Lynch's major entry into this sub-genre is specifically about achieving some sense of identity in a place that subverts identity on a regular basis, promoting some to stardom and discarding others. For Diane, one of the discarded, it's about wish-fulfillment, dreams come true. Which is, in the end, if not reality, Hollywood. All the rest -- magic keys and scary old people and dimly lit apartments -- are just the trappings of truth.
