Although this isn't 100% confirmed, it is widely believed that this Fantastic Four reboot movie - as produced by Fox - will be set in the same universe as Fox's popular ongoing X-Men movie franchise. With the recent news that the new Deadpool movie will be set in the X-Men movie continuity, the Fantastic Four could become the next non-mutants to invade the franchise. The potential for epic stories from the comic books expands exponentially if the Fantastic Four and their associated characters join Wolverine, Magneto, Professor Xavier and Mystique et al, as the likes of Doctor Doom, Mole Man, the Skrulls, Annihilus and Galactus could provide a non-mutant threat for our favourite mutant heroes, while the heroes will obviously gain new allies. All that said, the shared universe concept doesn't necessarily mean the two teams will ever crossover - and Fox have stated as much in that regard.
