The film is a spoof, and the first thing it takes the mickey out of is itself. The acting is deliberately bad, the sets are awful, but it's obvious from the get go that the actors are thoroughly enjoying their roles! Especially Rod Steiger, he positively relishes being Van Helsing the vampire hunter, and the picture of his bald head sticking out of the bath at the end of the film and delightful German accent, is hilarious.
This is black comedy, on the lines of Mr Sloane, rather than anything Murphyesque. It shows the history of vampire lore, taking to its next funny height by now including black vampires (The Cripps, a notorious black drugs gang). Now, no vampire will bite a black person, they're racially prejudiced so the Cripps get their transformation by having a communal sex session with a beautiful vamp, turned into hidious demon. That did the trick.
Keystone Cops type chases ensue with the vampires chasing to kill, a very low class vampire turned without permission, and on the trail of all is Van Helsing, begging the quarry to slow down, and employing one black gangster to help him destroy the vampires, and this Cripps needs a job!
It's a real family contribution, the great Danny Elfman does the music, his brother or cousin Richard, a close relative anyway does the directing and there is another Elfman on the credits too, although I haven't placed her yet.
It's so low budget as to be off the scale, and I think this movie was done for love rather than big bucks! It'll never make the big time, I just think the cast and crew really enjoyed it, and I do too.
