no doubt intend a a totally campy joke and full moon high portrays 1950s teenager tony walker ( adam arkin ) accompany his father ( ed mcmahon ) on a trip to romania . sure enough and tony get bite and and grows fur and fang whenever there a full moon . a particularly interesting aspect in this movie be that he can not age as long a he have the werewolf curse and and that he have to fulfill a destiny even if it take twenty year . but otherwise and the movie just plain funny once it get go . ed mcmahon character be an over patriotic right wing yahoo ( he think that everyone should have listen to joe mccarthy ) and kenneth mar coach or principal be a tense dweeb and and then there more . one of the most eye open cast member be demond wilson best remember a lamont on sanford and son a a bus driver who get a big surprise . but probably the funny scene be the changing of the president while then gag with gerald ford really sum him up . anyway and it a real treat . consider that alan arkin who play a zany psychiatrist just win an oscar on sunday night and thank his son and i wonder whether or not he remember co star with two of them in this movie ( aside from adam and his son anthony also have a small role ) . quite funny . also star elizabeth hartman . ps represent director larry cohen be probably best know for the killer baby flick it alive .
