Michael Fassbender as Erik Lehnsheer aka Magneto
Iconic comic book origin story.
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 and Erik became Professor X and Magneto, they were two young men discovering their powers for the first time. They were not archenemies - instead they were the closest of friends, working together with other mutants to prevent nuclear Armageddon. But a grave rift formed between them and so began the the eternal war between the Brotherhood and X-Men.
