'X-Men: First Class' Trailer

20th Century Fox has released the first movie trailer for Matthew Vaughn's X-Men: First Class on Facebook. Based on a story by original X-Men director Bryan Singer, the new film is a Casino Royale-style prequel/reboot of the comic book movie series. The story "charts the epic beginning of the X-Men saga, and reveals a secret history of famous global events." This first trailer gives a much better idea of what we can expect from this film. And it seems like it should calm fans worried that we wouldn't see much mutant action.

Official Plot 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 Lehnsherr 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 prevent nuclear 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.
