Just a few days ago, we brought you a report that Amber Heard (Zombieland, Drive Angry 3D) was reportedly in talks to play the young Raven Darkholme/Mystique in the upcoming Matthew Vaughn directed, X-Men: First Class and a rumor that Rosamund Pike (Surrogates) was up for the role of Emma Frost in the film.

CBM previously reported that Pike was actually in the running to play Charles Xavier’s assistant Moira MacTaggert and that Michael Fassbender (Inglourious Basterds, Jonah Hex) who was being courted for the role of Erik Lehnsherr/Magneto had reportedly declined the offer to screen test for the role.

Now, EW is reporting that Fassbender is indeed still in negotiations to play Erik Lehnsherr/Magneto in the film and Showbiz411 is reporting that Benjamin Walker (Flags of Our Fathers, The War Boys) has been cast as Hank McCoy/Beast in the 20th Century Fox film, alongside James McAvoy as Professor Charles Xavier.

X-Men: First Class is slated to hit theaters on June 3rd, 2011.
