Full Moon High on AllMovie

This oddball werewolf outing from hit-and-miss genre auteur Larry Cohen details the comic misadventures of Tony Walker (Adam Arkin, son of Alan), a former high-school jock who is transformed into a werewolf during a family visit to Transylvania. Cursed with immortality, Tony is able to return to his old school stomping ground twenty years later and pass himself off as his own son. The outcome proves more disconcerting for Tony than for his unsuspecting friends, to whom the passing years have been less than kind. Ed McMahon co-stars as Tony's dad.
