While the X-Men franchise may be due for a cast changeover in the near future, director Bryan Singer is ensuring that the next installment, X-Men: Apocalypse, is stacked with fan favorites. Michael Fassbender, James McAvoy, Jennifer Lawrence, and Nicholas Hoult are due to reprise their roles from X-Men: First Class and X-Men: Days of Future Past, but Apocalypse marks the third and final film for which they’re under contract, so they have the ability to depart the franchise after this movie if they wish. Indeed, Lawrence recently revealed that Apocalypse will be her final X-Men movie, but the ensemble is also being filled out by younger versions of plenty of new mutants.

The latest addition is actress Lana Condor, who Singer revealed on Instagram will be playing the character Jubilation Lee—aka Jubilee. She joins previously announced new additions Tye Sheridan (Cyclops), Sophie Turner (Jean Grey), Alexandra Shipp (Storm), and Kodi Smit-McPhee (Nightcrawler), who are all playing young versions of characters that played a major role in Singer’s first two X-Men films. This signals that the filmmaker is gearing up to expand the “young X-Men universe” in the 1980s-set X-Men: Apocalypse, and it also ensures that if Fassbender, McAvoy, and Hoult also opt to depart, the franchise won’t be out of established characters.

Additionally (and unofficially), a new rumor purports to reveal a few cameos set for X-Men: Apocalypse. Latino-Review reports that the movie will feature appearances by Hugh Jackman’s Wolverine, Halle Berry’s Storm, and the debut of Channing Tatum’s Gambit, who’s getting his own spinoff movie set for release on October 7, 2016.

We revealed that Jackman would be part of the Apocalypse ensemble last year, and the idea that Tatum would debut Gambit with a cameo in the film makes perfect sense as a sort of teaser for his own film, as X-Men: Apocalypse is set for release on May 27, 2016. So it stands to reason that Latino-Review’s sources are solid.

The Apocalypse ensemble will also include Oscar Isaac as the titular villain and Rose Byrne reprising her X-Men: First Class role, so the movie is certainly shaping up to be a crowded affair. Singer did a solid job of handling two different casts in Days of Future Past, though, so there’s little reason to worry. I expect we’ll hear a few more “young mutant” additions as production nears its start date of April 28th in Montreal.
