"X-Men: First Class" producer Lauren Shuler Donner spoke to IAmRogue and cleared up the confusion regarding the other Emma Frost (played by Tahyna Tozzi) in "X-Men Origins: Wolverine." She also thinks Jones did a "pretty good job" in the role.
Is January Jones’ Emma Frost somehow the same character we saw in X-Men Origins: Wolverine?
Donner: No, she’s Emma from First Class. That’s who she was and she’s the real Emma Frost. I think January did a pretty good job of portraying her.
So there is no connection between the First Class Emma Frost and the one we see in X-Men Origins: Wolverine?
Donner: No … not really, no.
During the X-Perts Facebook campaign, Bryan Singer also said liberties were taken for the advancement of the story - which can be found in the FAQ.
"X-Men: First Class" comes out on DVD and Blu-Ray September 9, 2011!
