When it comes to X-Men First Class, the only thing we know for sure is that Matthew Vaughn will direct and James McAvoy will play Professor Xavier. Beyond that rumors have been flying that Michael Fassbender could star as a young Magneto, Rosamund Pike might portray Emma Frost/Moira McTaggert, and the newest tidbit has Amber Heard stepping into the role of Mystique.

Mystique is a blue shapeshifter, who in the comics was the mother of Nightcrawler, Graydon Creed, and Anna Marie aka Rogue. Her government name is Raven Darkholme and she was previously played by model-turned-actress Rebecca Romijn in the original X-Men trilogy. According to The Playlist via Production Weekly, 20th Century Fox is interested in having Heard take over the role in their adaptation of First Class.

I’m vaguely familiar with the First Class comic but I don’t remember Mystique popping up in any of the issues. The film could show her humble beginnings with Magneto, which would be a nice set up for the established relationship they have in X-Men 1. Either way, nothing’s been set in stone and the studio has yet to confirm anything. For now let’s just speculate on these candidates and see who makes the final cut.

X-Men First Class opens in theaters nationwide on June 3, 2011.

What do you think of Mystique possibly appearing in First Class? Is Amber Heard a good choice?
