A cool idea for GB3 can be when Louis and Dana actually “did” it in the first movie and that later Dana had Oscar. Now since Dana had Oscar, lets say Oscar has some sort of supernatural force in him because it wasn't Dana and Louis that had the baby, it was the Keymaster and the Gatekeeper. So in GB3, when Oscar is grown up, he gets this power to either act like Gozer or summon Gozer back to life.
This probably won't work because of the years between 1 and 2 when Dana had Oscar. Just thought it would be a cool idea.

Not bad. (*winston)

That is actually a good idea. Plus him being 1/2 possesed by Vego in part two, could just add to the mix. I think you should go ahead & write a ful scrpit on that idea. I could help you with a few ideas taht I've com eup with, if you like. perfect_one2k3@hotmail.com email me if you are interested.
