This isn’t a spoiler, but fans of the original X-Men films would probably get a kick out of it. With that said, Fox has released a new promo clip featuring Magneto and Mystique from “X-Men: First Class” which is set to open in theaters today! It seems innocent enough, but contained within these 60 seconds is another special guest cameo. It’s pretty obvious who, but it’s more fun if you don’t try to guess and just watch…

Here’s the official film 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. Starring James McAvoy, Michael Fassbender, Kevin Bacon, and January Jones, the film releases June 3!
