Deadline's Mike Fleming says that Fox wants actress Alice Eve for the (not especially) sought-after role of Emma Frost, aka (but probably not in the movie) "The White Queen," for Matthew Vaughn's "X-Men: First Class," which apparently no one can confirm as being either a "reboot" or a second-prequel following the disasterous "Wolverine" movie. Either way, it's a "teen years" story for the main group, with Michael Fassbender and James McAvoy as less-old versions of Magneto and Professor X.
Exactly how the "prequel" angle would work when we've already seen Magneto and Xavier as "middle aged" men coming to collect Jean Grey as a young girl in the third movie (she's presumably the same basic age as the rest of the "first class"), unless maybe their taking the opportunity to wipe EVERYTHING from "The Last Stand" completely out-of-continuity, which would actually be fine by me. (FWIW, Frost appeared sans last name via a different actress as "diamond skin girl" in the Wolverine movie.)
If the boxoffice is any indication, you probably DON'T remember Eve as "She" in "She's Out Of My League." In any case, fans can now begin The Procedure of processing this information which, in case you're wondering, goes something like this:
PHASE 1: Awareness.
PHASE 2: Excitement.
PHASE 3: Realization that there's almost no chance she'll wear The Costume, thus negating two out of three reasons anyone gives a shit about this character being in the X-Men movies.
PHASE 4: "So is Wolverine in this one or not?"
