Making Monsters #24: Ghostbusters
That these and the rest of the ghosts in the film are very believably brought to life by effects supervisor Richard Edlund and his company, Boss Films, makes Ghostbusters a very unique comedy. Usually, even with some of the funniest comedies, the production value, cinematography, effects and other elements become secondary to capturing the performances. It's a valid and often effective approach, but when a comedy like Ghostbusters actually puts the effort into making its fantastic scenario credible, Bill Murray's wisecracks actually become funnier in the context of a legitimately high-stakes story. Building on techniques Edlund developed on Poltergeist, the crew on Ghostbusters would combine multiple elements - miniatures, blue-screen photography, travelling mattes - in a single shot to make each scene work (this is before digital compositing, when composite shots had to be acheived directly on a photochemical negative). Even a ghost like Slimer (called "Onionhead" by the first film's cast and crew, he got his name from the Real Ghostbusters cartoon) that is meant to be purely comedic works better as a gag because of the effort Edlund and his crew put into selling the effect.
This is especially true in Ghostbusters' finest moment, the reveal of the Stay-Puft Marshmallow Man. Bringing the jolly-looking demonic manifestation of the Ghostbusters' certain doom to life required combining multiple effects techniques. A full-size Stay-Puft suit with animatronic facial expressions controlled by a team of puppeteers stomped model cars on a minature set of the city. Individual elements like cars and people running out of Stay-Puft's path were shot seperately and composited into the shot with the travelling matte techniques that Edlund and others developed on the original Star Wars trilogy. This was then combined, via matte, with shots of the Ghostbusters atop a skyscraper. The effect is both hilarious and jaw-dropping, almost unmatched in film for its sheer large-scale absurdity. It's funny, but if any of use ever saw Mr. Stay-Puft headed our way, we'd be as terrified beyond the capacity for rational thought as Dr. Spengler.
