The casting seems pretty good:
Jerry Dandridge - Colin Ferrell
Mom - Toni Collette
Charlie Brewster - Anton Yelchin
Evil Ed - McLovin
Peter Vincent - David Tennant
The setting has been moved to Vegas, and Peter Vincent is now a Criss Angel-type magician. I can see Tennant pulling that off, and I guess I don't mind the update as far as that goes.
However, CC2K has a script review here: http://www.cc2k.us/index.php?option=com_content&task=view&id=2115 that really disappoints me.
