Ghostbusters (titled on screen as Ghost Busters) is a 1984 sci-fi horror comedy film about 3 parapsychologists who are fired from Columbia University in New York and start up their own business investigating and eliminating ghosts. It was the second-best grossing movie of 1984 and was followed by a sequel, Ghostbusters II (1989), and 2 animated TV series, The Real Ghostbusters and Extreme Ghostbusters. The films sparked the catchphrases Who you gonna call? Ghostbusters! and I ain't 'fraid of no ghost, both from the hit theme song written and performed by Ray Parker, Jr.
