Famke Janssen Makes Triumphant Return as Jean Grey in Avengers: Doomsday, X-Men Writer Reveals

Alright, Marvel fans — grab your calendars and your mutant bingo cards, because the next couple of years are shaping up to be absolutely bonkers in superhero movie land. Big screens are about to get even more crowded with capes, claws, and a bunch of characters you thought you’d already said goodbye to (several times). Here’s what’s bubbling up around Avengers: Doomsday and a possible mutant renaissance — with some actual, eyebrow-raising inside info direct from comic legend Chris Claremont.

Famke Janssen Is (Allegedly) Back as Jean Grey

You know her as the Bond girl in GoldenEye, but to a lot of us, Famke Janssen will always be THE Jean Grey — and apparently, she’s dusting off the Phoenix for Avengers: Doomsday. If you’ve been tracking all the leaks and rumors, you’ve probably noticed that Marvel’s pulling in just about every hero they have a rights contract for, including the Fantastic Four and the X-Men. But until now, it wasn’t clear if we’d get some OG Fox X-Men faces. Then Chris Claremont — as in, the Chris Claremont — decided to spill that particular bean.

The comic book icon took to X (yep, what used to be Twitter) to hype up those familiar, comic-accurate mutant suits we glimpsed in that teaser. Buried in the excitement, he summed up the biggest casting flex Marvel could make:

The thing I found most wonderful about it is that they are bringing back the original cast, including Famke.

Need a refresher? Janssen played Jean Grey across three X-Men movies — the originals from the 2000s, not the recast timeline weirdness. That’s X-Men (2000), X2 (2003), and The Last Stand (2006).

Chris Claremont Is on a Spoiler Spree

Here’s where things get wild. Claremont isn’t just goofing around on social media — Comic Book Movie reports that he dropped even more potential spoilers during a convention appearance at the Huntsville Pop Culture Expo back in April 2025. The man sounded like someone who’d been handed a very juicy script and couldn’t keep his mouth shut. Here’s the rundown:

• Robert Downey Jr. is supposedly coming back not just as Tony Stark, but also as Dr. Doom (?!), so expect a full-on multiverse duel. Apparently, he’ll suit up as Iron Man too. No, none of that makes sense yet.
• Chris Evans is returning as Captain America, and he might share the screen with alternate versions — a young Steve Rogers, and even Captain Hydra for those who like their timelines extra confusing.
• Elizabeth Olsen will be back as Scarlet Witch, and this time she’s playing nice (for once).
• And, Claremont claims, Wolverine 'will kill somebody important.' Who and why? He’s not saying. But prepare for a big-deal snikt moment.

To be clear, these aren’t just leaks; these are the words of the writer who basically made the X-Men what they are. And with all signs pointing to a soft reboot for the MCU after Avengers: Secret Wars, these curveballs suddenly seem plausible.

Chris Claremont: From the Sidelines Back to the Spotlight?

Now, here’s a detail only long-time comic nerds will appreciate: Claremont, despite his legendary status (he co-created Wolverine, Rogue, Mystique, etc.), hasn’t had much going on with Marvel lately. Bleeding Cool even pointed out that he didn’t have anything to write in 2025. That looks to be changing in 2026 — rumor is, Marvel might put out two brand-new projects from the guy for his 76th birthday year. If you love classic X-Men, this is the kind of news that gets you out of bed in the morning.

The Next Big Dates

If you’re the type that likes to plan a year ahead for movie marathons:

• Avengers: Doomsday is scheduled for December 18, 2026
• Avengers: Secret Wars hits theaters December 17, 2027

Honestly, if even half this stuff pans out, these movies are going to make Endgame look like a warm-up act. Famke Janssen back as Jean Grey, old-school X-Men meeting the Avengers, surprise deaths, wild multiverse shenanigans — yep, Marvel’s going full kitchen sink here.

Let me know in the comments if you’re hyped for Janssen’s return, or if you’re more interested in watching these timelines try to untangle themselves on screen.
