X-men First ClassUnite all you X-Men geeks and gather 'round as the moment has arrived that we finally get to see the highly anticipated trailer for X-Men: First Class. The film stars a whole gaggle of A and B-listers including Jennifer Lawrence, James McAvoy, January Jones, Rose Byrne, Michael Fassbender and others. The film, which represents the 4th installment in the X-Men big screen adaptation series, will feature the origin stories behind Professor X and Magneto and is slated for a June 3 release of this year.

The trailer first appeared on the Facebook.com/XMenMovies fan site, but you can see it below (after "liking" their page first, of course).

If the number of fans, "likes," and sharing of this trailer expands, new special content will become available through "a specially designed X-App" that will let Facebook users use some cool features that can be used to alter their profile pictures.

The Facebook page also reveals the confirmed X-Men: First Class movie logo.
