This idea i orginally had for Dark knight returns vs batman beyond controversy. So im molding this in. the movies at the theaters are literally rented and to pay that fee. Movie places charge around 6.oo (if your lucky). So if a shorter movie is made the system could be asked to change to a cheaper price.

So use 2 timelines in no continuity to each other. They could and should Make an hour movie (and charge less) of Ghostbusters where they uses extreme GB and shoot another movie around an hour long where they are older (of course use the same actors)and use that as the basis ( with no xgb charectors)

They would charge around 4.00 a movie each ( due to the shortness) and eventually hypothetically make more. (of course this will not happen but it is a good idea and there will be those diseagreeing with me below)

You must be an angel like Will Smith in Legend of bagger Vance or Slimer in GhosTbusters
