As the film establishing the movieverse origins of Marvel's merry mutans, X-Men: First Class is in the unique position of not only establishing backstories, but also new special effects for their powers. MTV's three new video segments spotlighting Alex Summers/Havok (Lucas Till), Sean Cassidy/Banshee (Caleb Landry Jones) and Hank McCoy/Beast (Nicholas Hoult) flesh out both halves of the equation and give fans one of their closest looks at the June 3 film yet. See for yourself after the jump.The three young mutants all face their share of tragedy. Havok's powers have hurt those closest to him, Beast is so driven to become normal that he accidentally becomes even more mutated-looking and Banshee... well, he's just got zero game. For a dude that age, that may well be the worst curse of them all.
