For a long while, it sounded like 20th Century Fox simply wasn't interested in connecting the X-Men and Fantastic Four franchises with a crossover movie. No plans have ever been confirmed to be in the works. Though back in October, Simon Kinberg did have hopes that it would someday happen. Now that the Fantastic Four reboot trailer has finally been revealed to the world, Kinberg, who is co-writing X-Men: Apocalypse, sounds even more optimistic. Talking with EW, he says:

"The reboot of FanFour really needed to work in and of itself. We were doing something pretty radical with the tone of the movie. If we wanted to find a way to connect them to the X-Men, we could. There's a lot of precedent from the comics."

Way back in April of last year, comic book writer Mark Millar, who is a consultant on both franchises, claimed that, while the two franchise might exist in the same universe, their movies would stand alone. And that's certainly the case as of now. But it looks like director Josh Trank has found a way to make both Mutants and these fantastic freaks of science co-exist in the same world.

Getting the Fantastic Four reboot right needed to happen before anyone involved with either property could think about merging the two titles. Back in October of last year, Simon Kinberg had this to say about where his focus was at the time:

"To be honest, I'm so focused on each of the movies right now - I'm so focused on Fantastic Four, and making that the best movie it can be. And then we're in prep on X-Men: Apocalypse, so those are kind of full time jobs. I love the characters, I love the characters in Fan Four, and I love the new cast. Obviously I love the characters and cast of X-Men. So, hypothetically, the notion of putting them together is really intriguing, and there's some really fun stuff that the comics have done in the past. So it's not out of the realm of possibility."

What do you think now that you've seen the Fantastic Four trailer? Does it look like these two properties were meant to co-exist on the same screen together? Or should they just stay in their own various corners of the Marvel universe? Sound off below!
