The class of mutants is assembling, ready for the release of X-Men: First Class on June 1st. Now another new film clip has emerged, where Charles Xavier (James McAvoy) is first introduced to a young Hank McCoy (aka Beast) and gets to see some of his powers. In the film, James McAvoy and Michael Fassbender star as young versions of Charles Xavier (Professor X) and Erik Lenscherr (Magneto), who were friends before becoming enemies. They had a lot to deal with in the 60s, when a new species of mutants was emerging and the world was on the precipice of nuclear war.
