Here's the first trailer for X Men first class! For those not in the know the cuban missle crisis sets the stage for the events that unfold within the mutant community and the divide between Charles Xavier and Eric Lehnsherr is fleshed out in this storyline. From my few viewing so far I have spotted Beast, Mystique, Emma Frost, and Psylocke. Aside from the glaring date/age continuity issue with Emma frost I think this looks pretty good.
Personally I'm more excited for the new Spiderman movie starring Andrew Garfield!!
