During a recent interview, writer Simon Kinberg revealed that the relationship between Jennifer Lawrence and Nicholas Hoult’s characters will be at the center of X-Men: Apocalypse.

“The relationship between Beast and Mystique is a really interesting one that we didn’t have a lot of time to explore in Days of Future Past, so we’ll have an opportunity to do more of that in Apocalypse,” Kinberg told Collider.

Mystique’s mindset was explored a bit in Days of Future Past, but fans will get an even deeper look at how the mutant was affected by growing up under the tutelage of Professor X and Magneto.

“Part of what’s really interesting about Mystique’s character is that she is, in some ways, the child of both Erik and Charles,” Kinberg added. “She grew up with Charles and then she sort of became a woman with Erik, so her being the cross-pollination, if you will, of those two philosophies and those two men is something we can explore in the movie, too.”

Focusing the movie on two characters who have not played large roles in the series so far feels like a ploy to keep popular actress Jennifer Lawrence at the center and hopefully bring additional eyes to the franchise. James McAvoy and Michael Fassbender are expected to return as Charles Xavier and Erik Lehnsherr, but there may also be a few new faces.

Bryan Singer will return to direct the film.

X-Men: Apocalypse will premiere May 27, 2016.
