This is partly me posting a video that has been all over the web for months but that I have only just found, and partly me playing around with imbedding videos.
This is a trailer for the Shining (brilliant film) recut to make a heartwarming family drama out of it. Whether it is a travesty or not is debatable, but it's quite funny.
http://youtube.com/watch?v=ipuqHA6Jmh4Some of these are also worth checking out:
West Side Story as a Zombie Flick - Not that much use of actual footage but not bad.
Sleepless in Seattle as a Thriller - Nice use of footage but rarely believable.
Titanic as a Horror Film - Funny concept but it doesn't actually work that well
Psycho as a Romantic Comedy - Relies too much on the voiceover but works quite well
Eternal Sunshine of the Spotless Mind as a Horror Film - Some fairly deft editting marred somewhat by an overly-obtrusive voiceover.
Cabin Fever as a Drama< - If you haven't seen the original it's a average at best horror film. This actually looks more watchable than the original.
Gandhi as a Comedy - You need to log in to see it. The user name is holy, password is cow. I really wouldn't bother. It isn't any good.
There's also about 50 Brokeback Mountain/Insert film here edits. None are really worth linking to.
