What if...Ghostbusters, the movie, was shot in 1954 instead of 1984? Who should be part of the cast? Would they have the same equipment? Who would they battle? Considering Dan Aykroyd's concept owes a lot to Bob Hope, Abbott and Costello, and Lewis and Martin comedies of the 40s and 50s, it is not that big of a stretch to speculate.
Here's the recipe for the trailer:
Ghostbusters, The Three Stooges, Scared Stiff, Ghost Breakers, Topper Takes a Trip, The Ghost Busters, Abbott and Costello meet the Invisible Man, Star Trek, Ghosts on the Loose, The Day the Earth Stood Still, Spooks Run Wild, Flubber, Son of Flubber, The Caddy, 100 ans d'histoires de Bibendum
