Mulholland Drive is a great film. If you haven’t watched it yet, just watch it.
Those lucky enough to be astounded and puzzled by the film have all came up with their own interpretation of the movie.
The most common interpretation is that either the first or the last part is a dream of the opposite part. I’d have to disagree with that for both parts are just too bizarre to be real. However, both parts are pseudo-opposite.
Just take the ‘119’ on the firetruck for instance that hasn’t been mirrored, but still reversed.
It keeps you thinking in any case.
