Yes, as the rumor mill has purported, "X-Men" franchise alums James Marsden, Famke Janssen, and Halle Berry could be up for a collective big-screen comeback via "Deadpool 3." Given that both Marsden's Cyclops and Janssen's Jean Grey both died in "X-Men: The Last Stand," it's a bit of a head-scratcher that they'd have any chance of returning. Then again, it's not as impossible as it may seem for two big reasons.
For one, the "X-Men" movie timeline got a big shakeup thanks to 2014's "X-Men: Days of Future Past." In the film, Wolverine travels back in time to prevent an apocalyptic future that nearly wipes out all of humanity and mutantkind alike. He's successful, and when he returns to the present day, he's greeted by the previously-deceased Cyclops and Jean. Therefore, working on the assumption that the "Deadpool" trilogy exists in this timeline, it's not a stretch to assume that they and Berry's Storm could make appearances.
In the event that "Deadpool 3" takes place in an entirely different continuity, it's still possible for Marsden's Cyclops to appear. The Marvel Cinematic Universe is currently all about the multiverse, converging timelines, and time travel. Perhaps using the time travel device he "borrowed" from Cable (Josh Brolin) in "Deadpool 2," Deadpool (Ryan Reynolds) will travel through time and space and eventually run into Cyclops, Jean, Storm, and Wolverine, who has already been confirmed to be a major player in the highly-anticipated threequel.
We'll just have to wait and see if and how James Marsden's Cyclops will appear in "Deadpool 3" when the film arrives on May 3, 2024.
