Ghostbusters
Ghostbusters is a 1984 American supernatural comedy film directed and produced by Ivan Reitman and written by Dan Aykroyd and Harold Ramis. It stars Bill Murray, Aykroyd, and Ramis as Peter Venkman, Ray Stantz, and Egon Spengler, respectively, a trio of eccentric parapsychologists who start a ghost-catching business in New York City. The film also stars Sigourney Weaver and Rick Moranis, and features Annie Potts, William Atherton, and Ernie Hudson in supporting roles. Based on his own fascination with spirituality, Aykroyd conceived Ghostbusters as a project starring himself and John Belushi, in which they would adventure through time and space battling supernatural threats. 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.
