When asked about the potential for a Fantastic Four/X-Men crossover,Miles Teller, who plays Mr. Fantastic, said,

I think Bryan is a great director and I love the X-Men films. I don’t know how that would work. If someone can come up with a world where that works and it’s not just trying to combine a bunch of franchises to make money, then I think that’s great.

Jamie Bell, who plays The Thing,said:
To be honest with you, I think the X-Men franchise is a good template for how to keep something feeling new, fresh and good.
