And she wasn't even the original casting choice, anyway.
Is the character Emma Frost returning? Leaving it a bit late for recasting. I don't think the character is returning (amongst others) and yet she (and others) joined Magneto at the end of First Class. That tells me they had an idea about a sequel to First Class and then jumped ship at the last minute.
