Which point of the film it would set, which characters included and what would happen?
COUPLE OF RULES:
1.) It should not permanently change the storyline/outcome of the film as we see today. As in it should add to the film's story in some way, and not change/alter it.
2.) Nothing from the books, comics or the sequel films because they weren't even dreamt about when this film was being written.
As in the point is to put ourselves in the script writers' shoes as they were making the film in early '90's and have all the scenes that happen in the film, happen, but add one scene in it that you'd like to have seen. (No need to write the scene in any creative way, just generally tell us about it.)
