Yes, that cast does exist within one movie, the wonderful D.C. Cab. If you weren't convinced already by the casting of Mr. T and Gary Busey together, then I will tell you this - This marvelous movie was written by Joel Schumacher. Yes, the man that gave Batman nipples in those terrible Batman movies. Even Bill Maher, Otis Day, Paul Rodriguez, The Barbarian Brothers, and Bob Zmuda have some screen time in this picture. What's crazy is the movie tries to teach racial equality, but just comes off completely racist. Then there's also a flame thrower for absolutely no reason, an amazing speech given by Mr. T in front of the Lincoln memorial, and a plot that changes so much that in retrospect you have no idea what the movie was about. You must watch this movie. So bad that it's entertaining.
