“Ghostbusters” (1984) is a comedy-horror film directed by Ivan Reitman and written by Dan Aykroyd and Harold Ramis. The film stars Bill Murray, Dan Aykroyd, Harold Ramis, and Ernie Hudson as a group of eccentric parapsychologists who start a ghost-catching business in New York City. With its unique blend of humor, supernatural elements, and memorable characters, “Ghostbusters” has become a beloved classic.

The story begins with three scientists—Dr. Peter Venkman (Bill Murray), Dr. Raymond “Ray” Stantz (Dan Aykroyd), and Dr. Egon Spengler (Harold Ramis)—who study the paranormal at Columbia University. After losing their university funding, they decide to go into business for themselves and create the Ghostbusters, a company specializing in capturing and containing ghosts.

They set up their headquarters in an old firehouse and develop high-tech equipment to capture ghosts, including the iconic proton packs and the ghost containment unit. The Ghostbusters’ first major client is Dana Barrett (Sigourney Weaver), a musician who experiences supernatural disturbances in her apartment, including a demonic presence in her refrigerator.

As the Ghostbusters’ fame grows, they hire a fourth member, Winston Zeddemore (Ernie Hudson), to help manage the increasing demand for their services. The team soon discovers that Dana’s disturbances are connected to an ancient Sumerian god named Gozer, who plans to bring about the end of the world.

The climax of the film involves the Ghostbusters confronting Gozer, who manifests as the Stay-Puft Marshmallow Man, a giant, destructive creature made of marshmallow. Using their proton packs, the Ghostbusters manage to defeat Gozer and save New York City from certain doom.

“Ghostbusters” is renowned for its witty script, innovative special effects, and the chemistry between its lead actors. Bill Murray’s performance as the sarcastic and charming Peter Venkman stands out, providing much of the film’s humor and charm. The film also features memorable supporting performances from Rick Moranis as the nerdy Louis Tully and Annie Potts as the Ghostbusters’ no-nonsense secretary, Janine Melnitz.
