One of the most anticipated films of 2015 is X-Men Apocalypse, which is reportedly focusing on the character of Mystique, played by actress Jennifer Lawrence. The character saw major screen time in the previous installment of the series, X-Men: Days of Future Past, and is apparently going to be explored further in the new film, according to co-writer Simon Kinberg.

Kinberg, who is also co-producer of the film, said that X-Men: Apocalypse will be featuring in more detail the relationship between Mystique and the character of Beast, played by actor Nicholas Hoult. “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,’” said Kinberg.

X-Men: Apocalypse will also reportedly show how Mystique was shaped by her two mentors, Michael Fassbender’s Magneto, AKA Erik Lensherr, and James McAvoy’s Charles Xavier. “Part of what’s really interesting about Mystique’s character is that she is, in some ways, the child of both Erik and Charles. She grew up with Charles and then 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,” Kinberg said.

Kinberg also revealed that X-Men: Apocalypse will be set in the 1980s. “We’re having a lot of fun with the idea of the ‘80s. It’s a decade that [director Bryan Singer] and I both grew up in, and so the music, the style, the aesthetic [and] the legacy of ‘80s movies is something we’re really having fun with,” he said.

X-Men Apocalypse will also be the third and final part of the trilogy featuring characters from X-Men: First Class, Kinberg said, although he didn’t rule out their appearances in future X-Men films.
