X-Men:First Class has another casting in the form of Benjamin Walker (Kinsey, Flags of our Fathers) as the furry, blue genius with insane acrobatic skills, Beast. A fan favourite, Beast was previously played by Kelsey Grammar in X-Men: The Last Stand
(which I thought was great).
Walker joins already cast, James McAvoy (Professor X) and other front runners, Rosamund Pike, Amber Heard, Aaron Johnson and Frank Dillane for the origins story that will show the formation of the X-Men through Charles Xavier and Eric Lensher and their subsequent destruction as the founders fall apart and eventually go to war as Professor X and Magneto.
