My nomination is the always entertaining, Wings Hauser. I believe he has the longest string of horrible film without, even by accident, being in a good movie! With films like Street Asylum (1990), Bedroom Eyes II (1990) and Beastmaster 2: Through the Portal of Time (1991), how can anyone beat him?
Well, maybe not beat him, but his son Cole sure isn't a master thespian himself. His roles in the Cave and Paparazzi aren't going to be winning him any awards any time soon.
As for my own personal picks, I'd have to say both Brian Bosworth and Gary Daniels can be pretty bad to.
