Purple People Eater is a 1988 American science fiction comedy film based on Sheb Wooley's 1958 novelty song of the same name,[2] written and directed by Linda Shayne, and starring Neil Patrick Harris, Ned Beatty, Shelley Winters, Dustin Diamond, Peggy Lipton, and Thora Birch in her film debut.

That night, Billy starts playing the novelty song, and a one-eyed, one-horned flying purple alien from outer space appears and lands on a nearby tree.

Purple explains to Billy that he knows only classic hits because it takes twenty five years for radio waves to go from Earth to his home planet.

That night, Rita celebrates her birthday with her family, but Noodle shows up and ruthlessly gives her an eviction notice, causing her to pass out.

Billy and Purple plan to put up a benefit concert to save the homes of senior citizens on Labor Day.
