X-Men: First Class

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. Before they were arch-enemies, they were closest of friends, working together with other mutants to stop the greatest threat the world has ever known. The film follows their relationship as they deal with the Hellfire Club led by Sebastian Shaw, a mutant supremacist bent on starting a nuclear war in 1962 during the Cuban Missile Crisis.
