Interesting facts include: Slimer (no more than a green peanut in some shots) was inspired by Bluto from Animal House. They chopped up a hundred model police cars and converted them into Marchmellow Man scale taxis and fire trucks, yet none of them moved. Peewee Herman and Grace Jones were both considered for Gozer the Carpathian. Harder to imagine (but proved by original storyboards) is that John Candy was originally cast as Louis Tully. I am not quite sure why these effects people talk so much about casting. It's a nice little segment on the DVD, but on it's own just shy of a few hilariously shaped explosions. Still, this way it reaches more people than if they had made these people record an audio commentary.
