Reel Movie Nation – X-men: First Class-Will Rosamund Park land Emma Frost?

As filming for Matthew Vaughn’s X-men: First Class begins, so do rumors and speculations about casting. According to Forces of Greek, Rosamund Park may get the chance to play the sexy and tempting mutant-Emma Frost.
As any good actor/actress should do, Park was seen purchasing Emma Frost comic books at a local shop. She was also seen entering and exiting the offices of Lucinda Syon, casting director for Matthew Vaughn’s Stardust and Kick-Ass.
Pike recent films include: Surrogates, Die Another Day, and Doom. She’s a solid actress with the chops to back it up.
My Question… What is Emma Frost doing in X-men: First Class? We have no idea what Fox and Vaughn have planned for the muties… but I can’t wait to find out.
It may even be safe to say that the timeline for the X-verse may be a little off. I have a feeling that this Emma Frost won’t be nearly as innocent as the Emma in X-men Orgins: Wolverine.
What do you guys think?

Should Fox try to stay within the boundaries of the comic book and only include Beast, Angel, Marvel Girl, Cyclops, and Iceman?

Or should Fox follow their own plans and add mutants such as Emma Frost and whoever else may be instore?
