There is just over a month to go until the seventh instalment of the superhero franchise hits UK cinemas on 22 May.
Jackman is back as clawed antihero Wolverine, seen in the short clip gathering mutants for a desperate battle against time to save the future from doom.
“I was sent here for you from the future, 50 years from now,” he tells McAvoy’s Charles Xavier (the telepathic Professor X).
“Tell the person who sent me, I’m busy,” comes the stony reply, before Wolverine drops a bombshell: “The person who sent me, was you.”
Lawrence’s Mystique is also soon recruited. “We need you Mystique, you’re a cold-hearted b**ch,” Wolverine begs.
“Well don’t hold back,” she quips.
Cue lots of fighting, window-shattering, guns, lasers, you name it.
The original trilogy’s cast, including Sir Patrick Stewart and Sir Ian McKellen, will be teaming up with newer stars such as Michael Fassbender for Bryan Singer’s follow-up to 2011’s X-Men: First Class.
Ellen Page, Nicholas Hoult, Shawn Ashmore, Lucas Till, Daniel Cudmore and Halle Berry will also be returning in various roles.
Then, as if the line-up could get any more star-studded, Game of Thrones’ Peter Dinklage, Josh Helman, Booboo Stewart, Adan Canto, Omay Sy, Fan Bingbing, Evan Peters and Evan Jonigkeit all make their X-Men debuts.
