Gebissen Wird Nur Nachts (1971, GER) C-101m. *½ D: Freddie Francis. Starring Betty Williams (=Pia Degermark), Thomas Hunter, Yvor Murillo, Ingrid van Bergen, Joachim Kemmer, Ferdy Mayne. Low-brow vampire spoof, mostly inspired by Polanski's 1967 FEARLESS VAMPIRE KILLERS, made by British cinematographer-turned-director Francis with a largely German cast and crew. Hollywood star Williams inherits a castle in Transylvania and is confronted with her vampiric grandmother, a nymphomaniac. The emphasis is on visual gags and puns ("May I drive my stake into you?"). Tries hard to be frivolous, but comes off as obnoxious. Only has some value as a curio. Filmed in English. English title: THE VAMPIRE HAPPENING.
