Bryan Singer Says 'Fantastic Four'/'X-Men' Crossover Is "In Play"

Fantastic Four Trailer Still - H 2015
It's about time, it seems.

With three movies set for release next year, Fox is making full use of the X-Men cinematic universe — but director and executive producer Bryan Singer is hinting that universe might be larger than fans think, and include Josh Trank's Fantastic Four, as well.

Talking to Yahoo! Movies, Singer said that recent rumors of a crossover between Fantastic Four and the X-Men movies have some truth to them. "Those ideas are in play," he revealed. "That would be a natural match-up because they're both ensemble films and there is a natural mechanism by which to do it."

Quite what that "natural mechanism" is, however, Singer won't be drawn out on. "It deals with time," he teased. "That's all I'm going to say."

In addition to both teams being Marvel properties (and ones that have been paired on multiple occasions in comic books, most notably 1987's Fantastic Four vs. The X-Men series and 2009's X-Men/Fantastic Four), both movie franchises have an X factor — sorry — that would make a crossover easier: screenwriter and producer Simon Kinberg, who worked on the screenplays for X-Men: Days of Future Past, Fantastic Four and next year's X-Men: Apocalypse.

Fantastic Four hits theaters Aug. 7.
