It is very unlikely that Ghostbusters III will be made. But what if it was? Here are just a few ideas I came up with, just to make GB3 more of a possibility:
1) I have the address of Dan Aykroyd and is planning on writing to him the script I am working on one of these days.
2) Instead of re-release the original in 2004, why not make GB3 and release for that year.
3) The plot of GB3 would go like this: It is now fifteen years since the Vigo incident, and once again, the Ghostbusters are defunct. Ray has taken to lecturing college kids about paranormal studies. But then, strange occurences happen again that call for the Ghostbusters to be back in action. But instead of Egon, Peter, and Winston, Ray has called a new squad of GBs comprising of four of the college kids he has lectured. The movie will probably center on either Gozer coming back to wreck havoc, or a new monster.
4) The four new GB's I thought would probably be: Jason Biggs, Renee Zwelleger, Marlon Wayans, and Freddie Prinze, Jr.
5) Perhaps we could have Ray die in GB3, just as he is about to save the new squad.
6) I thought the new Ecto-1 would be the original updated, with more gadgets, and it will have features like the Bond cars.
How's this for a sequel, eh?
