harold will be the criminologist, izzy will be either janet or columbia, likewise sindi, karl will be riff raff or dr scott, stuart will be frank, liljana will be magenta. can't figure out who will play brad, eddie and the rest of them will be transelvanians. if holly valance is making a special appearance, she'll be the usherette and sing the opening song. this is based on my pathetic knowledge of all things rocky and my opinion of who would be best suited in each role.
