Ghostbusters is a 1984 American fantasy comedy film produced and directed 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, eccentric parapsychologists who start a ghost-catching business in New York City. Sigourney Weaver and Rick Moranis co-star as their client Dana Barrett and her neighbor Louis Tully.
Aykroyd conceived Ghostbusters as a project for himself and fellow Saturday Night Live alumnus John Belushi, with the protagonists traveling through time and space. Aykroyd and Ramis rewrote the script following Belushi's death and after Reitman deemed Aykroyd's initial vision financially impractical. Filming took place from October 1983 to January 1984. Ghostbusters was released in the United States on June 8, 1984. It received positive reviews and grossed $242 million in the United States and more than $295 million worldwide, making it the highest-grossing comedy film of its time. At the 57th Academy Awards, it was nominated for Best Visual Effects and Best Original Song (for the theme song). The American Film Institute ranked Ghostbusters 28th on its 100 Years...100 Laughs list of film comedies. In 2015, the United States Library of Congress selected the film for preservation in the National Film Registry, finding it "culturally, historically, or aesthetically significant". Ghostbusters launched a media franchise, which includes a 1989 sequel, two animated television series (The Real Ghostbusters and Extreme Ghostbusters), video games, and a 2016 reboot.
