Ghostbusters (1984)

Ghostbusters is a 1984 American supernatural comedy film directed by Ivan Reitman, starring Bill Murray, Dan Aykroyd, Harold Ramis, and Ernie Hudson as four eccentric parapsychologists who start a ghost-catching business in New York City. When an ancient Sumerian god named Gozer threatens to destroy the world through a portal atop a Central Park West apartment building, the Ghostbusters must save the city from a spectral apocalypse that climaxes with the arrival of a 100-foot Stay Puft Marshmallow Man stomping through Manhattan. Ghostbusters was the perfect fusion of Bill Murray's deadpan irreverence, Dan Aykroyd's genuine enthusiasm for paranormal lore, Harold Ramis's dry intellectual wit, and Ernie Hudson's everyman skepticism, creating an ensemble comedy that was far more than the sum of its parts.

Ray Parker Jr.'s title song became one of the most recognizable pop songs of the 1980s. The visual effects by Richard Edlund created ghosts that were both frightening and hilarious, and the proton pack streams became one of cinema's most iconic weapons. Ghostbusters earned $295 million worldwide on a $25 million budget, making it the highest-grossing comedy of 1984, and spawned a multimedia empire spanning sequels, animated series, video games, and toys.

The film's cultural impact was enormous — it demonstrated that comedy and special effects spectacle could coexist at the highest level.
