Set in the era before Professor Charles Xavier and Erik Lehnsherr became mortal enemies as Professor X and Magneto respectively, director Matthew Vaughn's X-Men: First Class follows the two former allies as they lead a powerful team of mutants on a mission to save the planet from nuclear annihilation. Charles (James McAvoy) and Erik (Michael Fassbinder) were just young men when it began to appear as if the world was careening toward destruction. And as the Doomsday Clock ticks faster toward midnight, the time comes to take action. In the process of saving humanity, however, Charles and Erik clash. In the years that followed, Professor X would lead the X-Men in the fight for good, as Magneto and the Brotherhood spread chaos and destruction through land. Kevin Bacon, Caleb Landry Jones, Nicholas Hoult, January Jones, and Lucas Till star in a film directed by Matthew Vaughn and adapted from a story by Bryan Singer.
