Now that Comic-Con is behind us, what do comic book junkies have to look forward to? Well, according to Collider, the answer is the X-Men: First Class sequel — which will include the back story of Michael Fassbender‘s character, Magneto.

In an interview with the film’s writer/producer Simon Kinberg, new details emerged about the comic book flick he calls “the most guarded state secret I’ve ever been around.”

The plan for the sequel — which he says “is unlike the other X-Men movies” — is to do some unexpected things with Xavier and Magneto. In February he told MTV, “Magneto becomes the villain ultimately of the franchise but he’s a much more complicated character as a young man. He’s someone you sympathize with, you care about, you root for even though you might not necessarily agree with his methods, you understand his philosophy.”

In the new movie, Magneto will have “a villainous side and he’ll have a sympathetic human side. You’ll be able to relate, but you’ll also be afraid of him.”

Kinberg has been working closely with director Matthew Vaughn and producer Jane Goldman on the script and they “hope to begin shooting in spring of next year to come out in July of 2014.”
