Recut
Here's the winner of an interesting contest: take a Hollywood film and cut a new trailer for it -- in a completely different genre. Robert Ryang won with a fresh cut of The Shining as a romantic comedy.
This was so convincing that I was wondering to myself, 'How could I have missed this unsual Jack Nicholson movie? And wasn't there a Steven King novel with the same title?'
A very interesting hypertextual exercise.
