As the original choice to play the role of the alien hunter itself in the movie 'Predator', he hit a few personal snags. For starters, he was not happy with the fact that his face would not be shown on camera, and that he would be having an uncredited special fx role. He was also not fond of the original monster suit...he frequently passed out due to heat exhaustion. Because he complained so much and was very uncooperative, he was fired from the film. When Stan Winston's Predator design came in, Kevin Peter Hall was chosen to play the title role and filled it perfectly. Supposedly, Van Damme has no regrets on backing out of the Predator project.
