10 Awesome Movie Franchise Crossovers We're Dying To See

6. X-Men & Fantastic Four

Why It'd Be Awesome: For starters, there's a very realistic prospect that it might happen. Simon Kinberg, who wrote both X-Men: Days of Future Past and the upcoming Fantastic Four reboot, declared, "I would love to see team up if only because I'm a fan and certainly it's something we've thought about and talked about." What's more, both movie properties are owned by Fox, so there aren't any nebulous legal issues to work out: this can actually happen, and just imagine how cool it could be. Why It Might Not Work: Kinberg pretty much hit the nail on the head himself by saying, "The challenge is that they essentially live in different universes. In the X-Men world of the movies, we never hear them talk about a famous super team called the Fantastic Four and in the Fantastic Four movie, they are fantastic because they are the only ones of their kind, meaning there aren't other people with super powers on the streets...So given that they exist in these different domains or dimensions there are some inherent challenges." Still, most audiences would probably be able to let that slide if we got to see Wolverine and co. teaming up with the quartet to take on a stable of famous villains, maybe led by Dr. Doom (presuming he's not just killed off in the upcoming Fantastic Four movie).
