Filming took place from October 1983 to January 1984, in New York City and Los Angeles. It was the first comedy film to employ expensive special effects, and Columbia Pictures, concerned about its relatively high $25–30 million budget, had little faith in its box office potential. Following Belushi's death in 1982, and with Aykroyd's concept deemed financially impractical, Ramis was hired to help rewrite the script to set it in New York City and make it more realistic. It also stars Sigourney Weaver and Rick Moranis, and features Annie Potts, William Atherton, and Ernie Hudson in supporting roles.īased on his own fascination with spirituality, Aykroyd conceived Ghostbusters as a project starring himself and John Belushi, in which they would venture through time and space battling supernatural threats. It stars Bill Murray, Aykroyd, and Ramis as Peter Venkman, Ray Stantz, and Egon Spengler, three eccentric parapsychologists who start a ghost-catching business in New York City.

Ghostbusters is a 1984 American supernatural comedy film directed and produced by Ivan Reitman, and written by Dan Aykroyd and Harold Ramis.
