Linda Shayne wrote and directed this children's story based on the 1958 novelty song "Purple People Eater" by Sheb Wooley. Billy Johnson (Neal Patrick Harris) is joined by a friendly alien from outer space who wants to play in a rock & roll band. Peggy Lipton plays Billy's mom, with James Houghton as the father and Ned Beatty as Grandpa. The band lends a hand to some senior citizens in their fight to keep their beloved retirement complex. Add Little Richard and Chubby Checker to the fun as the heroes try and stop the greedy landlord Mr. Noodle (John Brumfield) from kicking out the elderly residents. Only one word in the film gives the movie a PG rating instead of G. Watch for Sheb Wolley in a cameo role as the trapeze instructor in this low-budget family feature.
