Last year, we reported that writer-producer Simon Kinberg (X-Men: Days of Future Past) had been tapped to write a “Marvel-style” universe that would bring together 20th Century Fox’s two major superhero properties, X-Men and Fantastic Four because that’s what The Avengers hath wrought. Kinberg told THR, “I have a lot of ideas on how to build those brands and do what everybody is thinking of these days: Be like Marvel. I want to be able to build stories over multiple movies.” While Kinberg may still want to “build those brands”, he’s well aware that it’s not as easy as shoehorning them into the same story.
Speaking to ScreenCrush, Kinberg explained that there’s a logistical problem of having the X-Men and the Fantastic Four inhabit the same on-screen world because their powers come from different sources:
Because none of the X-Men movies have acknowledged the notion of a sort of superhero team — the Fantastic Four. And the Fantastic Four acquire powers, so for them to live in a world where mutants are prevalent is kind of complicated, because you’re like, “Oh, you’re just a mutant.” Like, “What’s so fantastic about you?”
That doesn’t mean Kinberg has ruled out the possibility, and I’m sure there at those at Fox who still want an X-Men/Fantastic Four crossover, although they might want to ask the good people over at Sony how that “more-is-better” calculation worked with The Amazing Spider-Man 2.
And while I’m sure comic book fans don’t see the problem of bringing the worlds together because that’s just how superhero comics roll, it’s a much tougher sell to a mainstream audience. It’s important to remember that just because superhero movies might be behemoths at the box office, that doesn’t mean everyone is now a geek who completely understands how these worlds work. When it comes to X-Men and Fantastic Four, I’m in favor of letting them go their separate ways.
