This is a fantastic film. It's a perfect parody of the American horror films of the 1930's to 1950's. The humour is camp, in the style of the the 1960's Carry On films. In fact, this film seems like an imitation of "Carry on Screaming", though I'm sure the similarity is unintentional. I laughed from beginning to end, both at the trashy jokes and the parody elements.
What's the film about? Elvira plays a stripper who has done a show in Transylvania in 1851. While on her way back to Paris her carriage breaks down, and she is picked up by a handsome stranger who takes her to Castle Hellsubus. Elvira is identical to the count's wife who died 10 years earlier under mysterious circumstances. The castle's inhabitants all have secrets and are following their own agendas. Brilliant!
