"To just say you're going to do it would be a mistake, you have to see how the films evolve before you make that decision to completely commit to that," he said, before admitting that there are conversations about it, and that there is a "natural mechanism" that can be used to make it work. "Those ideas are in play," he teased. "It deals with time. That's all I'm going to say."
It's hardly surprising that there would be ideas being thrown around, since 20th Century Fox have been wanting to bring its various Marvel characters together for a while, especially given the success of X-Men: Days Of Future Past (2014). Of course, while the likes of the X-Men and the Fantastic Four crossover all the time in the comics, and Marvel Studios have shown how it can be done on the big screen, there is still a lot of work to be done to bring the more disparate Fox properties together.
Can we expect to see some hints and clues sneaking into X-Men: Apocalypse? Or will the studio go the route of end credit scenes to establish connections? We will see for ourselves when Fantastic Four arrives on 6 August, followed by X-Men: Apocalypse on 19 May next year.
