28 DAYS LATER gets an extra ending. This is not an extra in DVD, but at the theaters.

This puts fear my belly because I had the similar idea. My cool idea, by my definition, was that I will have two or three endings for my film and let the viewers duke out who saw the "real" movie. It will be fun to have a seperate DVD release for each story arc associated with each ending, catoring to viewers' preferences: tragic, or happy-ending. Vox Populi may choose the winner judging by the ticket sales or DVD sales and the most watched version becomes THE version of the film.
