Oh, Jerry Warren. Duke of Schlocky Horror Films (he wasn’t prolific or notable enough to be The King).
The Wild World of Batwoman is a blatant rip-off of several films and a desperate attempt to piggyback on the popularity of the Batman television series of the 60s. It makes no sense, except for the fact that Batwoman and her Batmaidens fight evil by Go Go Dancing. This method is still used in the NYPD to this day.
At some point, Batmania wasn’t catching fire like it used to, so Warren changed the title to She Was a Hippy Vampire. Both trailers are included here, but no explanation for the movie’s plot could be found.
