“Ghostbusters” (1984, 1989)

Ghostbusters (1984) was a blockbuster comedy film, directed by Ivan Reitman, with a script by and starring Dan Aykroyd and Harold Ramis. Comic actor Bill Murray was the lead "ghostbuster," and his girlfriend in the film was the possessed Sigourney Weaver. There was a Ghostbusters II (1989) that was financially and critically less successful.

You've got to love any film that features ghosts in the New York Public Library.

The Academy Award-nominated song "Ghostbusters" was written and performed by Ray Parker Jr. The line is still remembered today: "Who you gonna call? Ghostbusters!"

Huey Lewis & the News sued Parker, claiming that "Ghostbusters" ripped off his song, "I Want a New Drug." This was settled out-of-court in an undisclosed agreement, although it was leaked that Parker had paid Lewis a lot of money.
