As one of the leading stars of X-Men: Dark Phoenix, Evan Peters promises a much darker tone for director Simon Kinberg's upcoming comic book adaptation.

Joining the likes of Jennifer Lawrence, Michael Fassbender and James McAvoy for X-Men: Days of Future Past in 2014, Peters plays Peter Maximoff, aka Quicksilver. Returning to the superhero ensemble after X-Men: Apocalypse in 2016, Peters says that the cataclysmic events of that movie are the least of the team's worries in Dark Phoenix.

Speaking with Collider, the 31-year-old explained how Kinberg is emphasizing the "dark" element of Dark Phoenix. "I think it’s the classic X-Men: First Class tone, where there’s a bit of humor thrown in there, but it’s much darker than the previous one, Apocalypse," he told the site.

Since becoming part of the X-Men movies, Peters' character has added humor and is largely remembered for his two slo-mo scenes set to "Time in a Bottle" and "Sweet Dreams" to lighten the tone. However, he wants to remind fans that Apocalypse was only setting the scene for how dark the franchise could become.

"Apocalypse was the ‘80s, so there was a lot of room for goofy stuff in there. This one is a much more serious film about the internal struggle of Phoenix and Jean, so it’s a dramatic film," Peters revealed. "There’s nothing very comedic about it, other than the few moments that are in there. I think it’s gonna be a powerful one. It’s Dark Phoenix. I think it’s gonna be darker than we’re used to. It’s gonna be a change, but it’s gonna be fun for everybody."

Apocalypse saw the arrival of Game of Thrones alumni Sophie Turner as a younger Jean Grey, while Dark Phoenix will effectively adapt the famous comic arc "The Dark Phoenix Saga" as the source material's second big screen outing after Brett Ratner's X-Men: The Last Stand. Jean's impending meltdown was briefly teased in Apocalypse, but Dark Phoenix is expected to see Turner's character fully adopt her Phoenix Force abilities.

Opening Feb. 14. 2019, X-Men: Dark Phoenix stars James McAvoy as Charles Xavier, Michael Fassbender as Magneto, Jennifer Lawrence as Mystique, Nicholas Hoult as Beast, Sophie Turner as Jean Grey, Alexandra Ship as Storm, Tye Sheridan as Cyclops and Kodi Smit-McPhee as Nightcrawler.
