Elves (1989)

This particularly bizarre horror variant on Joe Dante's Gremlins (1985) was directed by newcomer Jeff Mandel. The ridiculous plot concerns the efforts of a group of Nazis to set the stage for a Fourth Reich by mating one of Santa Claus' elves with a pretty teenaged waitress (Julie Austin). The cast is peppered with former television stars, including Deanna Lund of Land of the Giants as Austin's mother (she kills cats and has a nude scene) and Dan Haggerty of The Life and Times of Grizzly Adams as a drunken department-store Santa who used to be a detective. Even better is Haggerty's predecessor, a cocaine fiend who gets castrated by the Nazi elves. Mandel went on to co-direct Robo-C.H.I.C. (1989), which was almost as bad.
