Trivia: In the scene where Munson shows off his ring and throws a strike, notice three guys walk up to him. The first guy and the third guy to high five him are actually professional golfers, Billy Andrade, and Brad Faxon.
Trivia: In the fight scene between Roy Munson and Claudia, it's very obvious that actress Vanessa Angel's acrobatic stunts were performed by a much more muscular woman. The stuntwoman is Donna Keegan, who played the attempted-rape victim in "RoboCop" nine years earlier.
