The Real Ghostbusters was pretty faithful to the movies in terms of the main cast, but one minor addition made kids go gaga over the Ghostbusters- Slimer, who was friendly on the show and even helped the guys catch ghosts.
That hungry yet cute little ghost made the show a hit with kids, but as you can see in this unaired pilot for The Real Ghostbusters he was originally an enemy just like in the movie.
So if you've read this far you're probably wondering- what's the difference between the unaired pilot and the show we all loved to watch back in the day?
Well, here's the intro to the real show so you can see how the costumes and proton packs changed, and most of all how Slimer was portrayed as a gluttonous creep...as opposed to a gluttonous good ghost.
It is really hard to imagine this show without Slimer as a good guy, and what would 80s kids have done without their Hi-C Ecto Cooler?
