Status: Rumour. This one comes from Knight Edge Media and has not been confirmed by Marvel Studios or Cailee Spaeny’s team. Treat it accordingly, full credibility box below.
The Cailee Spaeny X-Men story may not be over. The Priscilla and Civil War star reportedly lost the role of Rogue to Inde Navarrette earlier this month, but a new report claims Marvel Studios liked Spaeny enough to keep talking, and that she is now in discussions to play a different mutant in Jake Schreier’s X-Men reboot. If true, one of the most in-demand young actresses in Hollywood would still be joining the MCU’s mutant era, just wearing a different costume than fans expected.
What does the new Cailee Spaeny X-Men report say?
Per Knight Edge Media, via ComicBook.com’s August 21 write-up, Spaeny is “currently in talks with Marvel Studios to take over the role of another mutant” in the X-Men film. No role is named in the report itself. ComicBook.com’s analysis floats Kitty Pryde as the cleanest fit, with Magik, Polaris and Jubilee as alternatives, all major X-Men who were conspicuously absent from the cast Marvel unveiled at D23.
That absence matters. Kevin Feige made a point of saying the D23 line-up was not the complete team and that more mutants would be cast before cameras roll. So there are real, unclaimed seats at the table, which is exactly the environment in which a report like this is plausible.
Who is already cast in the X-Men reboot?
Marvel announced the first wave of its new X-Men at D23 in mid-August. The confirmed names so far:
- Inde Navarrette as Rogue, the Obsession breakout who reportedly beat Spaeny to the part
- Adam Driver as Mister Sinister
- Christopher Abbott as Professor X
- Maya Boyd as Storm, a casting that already won the blessing of X-Men 97’s Storm voice actress
Jake Schreier, coming off Thunderbolts*, directs the untitled film, which is currently slated for 2028 and will introduce the first fully MCU-native X-Men team, separate from the Fox-era mutants expected to appear in Avengers: Doomsday this December.
Which mutant could Cailee Spaeny actually play?
Kitty Pryde is the obvious answer and the one ComicBook.com leans into. She is the classic audience-entry character for an X-Men story, young, brilliant, and central to decades of comics runs from Days of Future Past to Astonishing X-Men. Spaeny, who broke out playing quiet interiority in Priscilla and Alien: Romulus, fits that register far better than she ever fit Rogue’s southern brashness.
Magik would be the bolder swing, a fan favourite with a dark, demonic edge and strong ties to any future New Mutants or Young Avengers plans. Polaris and Jubilee remain long shots, but both would signal which era of X-Men stories Schreier is drawing from. Until a name attaches, the honest answer is: nobody outside Marvel knows, and the report does not claim to.
What happens next
If talks are real, expect either a trade confirmation from Deadline, Variety or THR in the coming weeks, or a quiet denial through the usual channels. Marvel still has several mutants to cast before the X-Men film shoots, and with Doomsday marketing about to consume all the oxygen, a casting announcement would be an easy win. We will update our rumour tracker the moment this one resolves either way.
