by David Lynch
This doesn’t happen often. Lynch’s TV show was developed, the pilot was shot, and then dropped. (Not that unusual.) But then Lynch got funding to shoot some more scenes, re-edit the film, and release it theatrically. Not only did it work, it went on to win awards.
The original TV pilot can be found online, taken from VHS source material.
A run-down of the differences in the pilot can be found at mulholland-drive.net
There is a fanedit in the works to recut the pilot from HD source material. Details can be found at fanedit.org
