Ready for more teen mutant angst with a period setting? X-Men: First Class is prepping a sequel, although your guess is as good as ours as to when it might take place — we’ve got our paws crossed for the 80s.
According to SuperHeroHype, the box office for X-Men: First Class wound up being enough to justify another flick.
The script is being written by First Class producer Simon Kinberg — who also wrote X-Men: The Last Stand. But don’t worry, when we talked to Kinberg, he seemed to have learned a lot from X3’s mistakes. So fingers crossed!
