It can be hard to hunt them down, but I'm super interested in finding martial arts movies that never made it past VHS. It's crazy to think just how many crappy movies got made in the span of 4 decades. Even prolific directors of bad films, like Godfrey Ho, don't actually know how many movies they made. He's gone on record as saying he and his team would make a new movie almost every week for years, and by the time a movie got out to some local discount theater, they'd have made 2 more movies already. Someone interviewed him years ago about one of his movies and he had no idea it was his until he saw his name on the box.
