Did Alice Eve Leave X-Men: First Class Because of Script Problems?
How did January Jones come to occupy the part in X-Men: First Class that had been previously tapped for Alice Eve? Comic Book Movie reports that Eve petitioned Fox to be let out of her contract after script changes left her unhappy with the direction and size of the role. Huh. Well, it's a good thing Jones has so much to do during her day job on Mad Men! Er, never mind. [Comic Book Movie via Cinema Blend]

After having to deal with Halle Berry's (aleged) demands for the second and third films, they were probably only to happy to let a potential diva in the making go.
Eve should ask Rachael Taylor about the wisdom in opting out of a franchise movie when you're barely known. Taylor turned down an offer to reprise her role in Transformers 2, and hasn't been heard from since.
I remember reading something like this a few weeks back actually.
I work at https://theautographbank.com and had the pleasure to meet Alice Eve.
They were the nicest person I've ever met!
They took the time to take pictures, sign autographs and were truly very nice and approachable.
That is the reason I actually wanted to read this article!
