Previously unnoticed edit?
The conventional wisdom is that there are 10 cuts or edits during the course of the film.

I've just noticed another possible edit that I don't think anyone else has pointed out. When Rupert (James Stewart) tells Brandon (John Dall) that he would have carried the body down the stairs, the camera pans over to the doorway. If you look at the screen closely you can see a slight jump-cut just before Brandon walks into the frame saying "But you'd be seen."
