Check it out below, it drops some hints on the foe that Professor X, Magneto and other mutants band together to fight, which then creates the rift between the Brotherhood and the X-Men.

Synopsis:

“X-Men: First Class charts the epic beginning of the X-Men saga, and reveals a secret history of famous global events. Before mutants had revealed themselves to the world, and before Charles Xavier and Erik Lensherr took the names Professor X and Magneto, they were two young men discovering their powers for the first time. Not archenemies, they were instead at first the closest of friends, working together with other Mutants (some familiar, some new), to stop Armageddon. In the process, a grave rift between them opened, which began the eternal war between Magneto’s Brotherhood and Professor X’s X-Men.”

The film stars James McAvoy, Kevin Bacon, Caleb Landry Jones, Lucas Till, Jennifer Lawrence, Nicholas Hoult, Edi Gathegi, Jason Flemyng, January Jones, Zoë Kravitz, Bill Milner, Michael Fassbender, Álex González, Oliver Platt and Ray Wise.

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