The film that I've always been tempted to edit on my own is Crouching Tiger, Hidden Dragon. I love that movie, but I've always felt that its flow and pacing would be improved tremendously by dividing the long flashback in the desert into two parts: use the first half as a prologue to the entire film, up until the point when Xiou Long disappears into the desert, and then insert the rest of the flashback where it currently stands. This would: 1) Establish Xiou Long 's character from the beginning of the film. 2) Provide a more exciting opening, as opposed to the talky first reel that currently exists. 3) Prevent an overlong flashback from interrupting the flow of the story. The simple change, I think, would make Crouching Tiger a perfect film.

The Hulk would also benefit from a few judicious edits.
