Ghostbusters (franchise) - Development

Development

The concept of the first film was inspired by Dan Aykroyd's own fascination with the paranormal, and it was conceived by Aykroyd as a vehicle for himself and friend and fellow Saturday Night Live alum John Belushi. Aykroyd came up with Ghostbusters after reading an article about quantum physics and parapsychology in the American Society of Psychical Research Journal and then watching movies like Ghostchasers. Aykroyd thought, "Let's redo one of those old ghost comedies, but let's use the research that's being done today. Even at that time, there was plausible research that could point to a device that could capture ectoplasm or materialization; at least visually."

The original story as written by Aykroyd was much more ambitious—and unfocused—than what would be eventually filmed; in Aykroyd's original vision, a group of Ghostbusters would travel through time, space and other dimensions taking on huge ghosts (of which the Stay-Puft Marshmallow Man was just one of many). Also, the Ghostbusters wore SWAT-like outfits and used wands instead of Proton Packs to fight the ghosts; Ghostbusters storyboards show them wearing riot squad–type helmets with movable transparent visors. The original draft of the script written by Aykroyd was very large, compared to a "phone book" by director Ivan Reitman.

Aykroyd pitched his story to director and producer Reitman, who liked the basic idea but immediately saw the budgetary impossibilities demanded by Aykroyd's first draft. At Reitman's suggestion, the story was given a major overhaul, eventually evolving into the final screenplay which Aykroyd and Harold Ramis hammered out over the course of a few months in a Martha's Vineyard bomb shelter, according to Ramis on the DVD commentary track for the movie. Aykroyd and Ramis initially wrote the script with roles written especially for Belushi, Eddie Murphy and John Candy. However, Belushi died due to a drug overdose during the writing of the screenplay, and neither Murphy nor Candy could commit to the movie due to prior engagements, so Aykroyd and Ramis shifted some of these changes around and polished a basic, yet sci-fi oriented screenplay for their final draft.

In addition to Aykroyd's high-concept basic premise and Ramis' skill at grounding the fantasy elements with a realistic setting, the film benefits from Bill Murray's semi-improvisational performance as Peter Venkman, the character initially intended for Belushi. The extent of Murray's improvisation while delivering his lines varies wildly with every re-telling of the making of the film; some say he never even read the script, and improvised so much he deserves a writing credit, while others insist that he only improvised a few lines, and used his deadpan comic delivery to make scripted lines seem spontaneous.

With the first DVD release of the film on the 15th anniversary of the original theatrical release, many original concepts of the film were revealed, based on the storyboard artwork: Louis Tully was originally to be a conservative man in a business suit played by comedian Candy, but he was unable to commit to the role. The role was taken by Rick Moranis, portraying Louis as a geek. Gozer was originally going to appear in the form of Ivo Shandor as a slender, unremarkable man in a suit played by Paul Reubens. In the end, the role was played by Yugoslavian model Slavitza Jovan, whose Eastern European accented voice was later dubbed over by Paddi Edwards's.

Winston Zeddemore was written with Murphy in mind, but he had to decline the role as he was filming Beverly Hills Cop at the same time. When Murphy had the role, Zeddemore was going to be hired much earlier in the film, and would accompany the trio on their hunt for Slimer at the hotel and be slimed in place of Venkman. When Ernie Hudson took over, it was decided that he be brought in later to indicate how the Ghostbusters were struggling to keep up with the outbreak of ghosts.

In order to properly light the set for Gozer's temple and create the physical effects for the set, other stages needed to be shut down and all their power diverted over to the set. The hallway sets for the Sedgewick Hotel were originally built for the movie Rich and Famous in 1981 and patterned after the Algonquin Hotel in New York City, where Reitman originally wanted to do the hotel bust. The Biltmore Hotel was chosen because the large lobby allowed for a tracking shot of the Ghostbusters in complete gear for the first time. Dana Barrett and Louis Tully's apartments were constructed across two stages and were actually on the other side of their doors in the hallway, an unusual move in film-making.

A problem arose during filming when it was discovered that a show was produced in 1975 by Filmation for CBS called The Ghost Busters. Columbia Pictures prepared a list of alternative names in the event the rights could not be secured, but during the filming of the crowd for the final battle, the extras were all chanting "Ghostbusters", which inspired the producers to insist that the studio buy the rights to the name. For the test screening of Ghostbusters, half of the ghost effects were missing, not yet having been completed by the production team. The audience response was still enthusiastic, and the ghost elements were completed for the official theatrical release shortly thereafter.
