Ghostbusters is a 1984 science-fiction comedy film written by co-stars Dan Aykroyd and Harold Ramis about three eccentric New York City parapsychologists-turned-ghost exterminators. The film was released in the United States on June 8, 1984 and like several films of the era, teamed Aykroyd and/or Ramis with headliner Bill Murray. It was produced and directed by Ivan Reitman, who also directed Stripes, and stars Murray, Aykroyd, Ramis, Rick Moranis, Sigourney Weaver, Annie Potts, and Ernie Hudson.
The film was remade in 2016 with the lead roles filled with actresses. Unless a distinction is added to a listing, the references are directed toward the original film.
