Slimer is undoubtedly one of the most recognizable symbols and characters from the Ghostbusters franchise, and now thanks to the new film we know his back story.
You may have noticed that he DOES in fact get a cameo in the new film, and part of this involved revealing his back story but that part got left on the editing room floor.
Paul Feig created the story with Ghostbusters co-writer Katie Dippold:
Slimer was a gangster executed for killing a waiter who screwed up his order. Slimer started his afterlife as a more traditional ghoul, but was disfigured when the Ghostbusters were called to the restaurant he was haunting.
“When the Ghostbusters come in, they haven’t quite tested their equipment yet, so they haven’t got the levels right,” Feig says. “The proton beams are too hot, so it blows his legs off. Then it turns him green. He starts to distort, and so he becomes Slimer. Then he escaped out into the world.”
