I think I'm about the last person in the world to find these. But just in case I'm not.....
2 examples of how selective editing for movie trailers can make the film look like something it's not.
First up, a trailer portraying Titanic as a horror film.
Next, one making The Shining look like a romance.
I just found those today, so don't feel bad.
My favorite so far is the West Side Story one.
I've only just realised that I completely screwed up the links to both remixed trailers. Both fixed now.
