When Dr. Peter Venkman (Bill Murray) and his Columbia University colleagues (Dan Aykroyd, Harold Ramis, Ernie Hudson) are kicked out of their prestigious academic posts, they start a private practice as professional ghost-catchers. Although things do not start auspiciously for the three parascientists, their television advertisements finally pay off when beautiful Dana Barrett (Sigourney Weaver) contracts them. It seems her apartment has become the entryway for ghastly ghosts and goofy ghouls hellbent on terrorising New York City. Soon they're not just going to her rescue, but trying to rid the whole city of the slimy creatures. Ghostbusters hit US screens in June of 1984 and went on to become one of the most successful comedy films of all time, spawning a sequel and a popular animated series.
