Jamie Madrox, Multiple Movie?!

Peter David certainly likes the idea, based off what he saw in "Sky High":

Wow. Madrox would make a cool movie

I've come to this conclusion having taken Ariel to see 'Sky High.' There's a character in there named Penny who basically has the same power as Madrox...to split into replicas of herself. It's used to hilarious effect in the film since she serves as the entire cheerleading squad of the high school.
