Bat Dude and Throbin - The Sexx Capaders (1989) starring Beau Beaumont (his real name, no doubt) - director's name escapes me. It's definately NOT the kind of film to watch if you need/want to get your rocks off - BUT - it is so corny, that I would still recommend it for all it's silliness - the Joker is called "The Poker" in this take-off, etc.
oh yeah, shameless plea for email - if you wanna see more before I auction this off, lemme know.
