Marvel’s Avengers: Doomsday cast mystery deepens as Russo Brothers drop cryptic teaser and Doctor Strange’s role remains uncertain.

Avengers: Doomsday already sounds like one of Marvel’s craziest projects ever, and with Doctor Strange’s inclusion in limbo and a cryptic teaser from the Russos suggesting otherwise, we can’t help but speculate on multiverse connections, not to mention Fantastic Four connections and the return of Doctor Doom!
‘Avengers: Doomsday’ announcement – Cast reveal leads to questions
The Multiverse Saga, concluding saga for blah blah blah by Marvel Studios including the massive new blockbuster “Avengers: Doomsday,” arriving in theaters December 18, 2026. A cast list of 27 confirmed stars has already been announced, but Benedict Cumberbatch’s Doctor Strange is NOT on it and that has set tongues wagging.
Cumberbatch himself has only perpetuated the mystery by giving contradictory responses in the past few months. At first acknowledging he was in Doomsday, then hinting his story would take him to Avengers: Secret Wars and then doubling back: “Yes, I am in that one.” But he wasn’t on Marvel’s original cast list.
Asked again more recently, he answered impishly, “Who can say? “Perhaps they simply didn’t have enough chairs.” — igniting speculation that Marvel might be saving a shocking reveal for a second wave of cast announcements.
Russo Brothers Drop Cryptic Teaser
Compounding the chaos, Avengers: Infinity War and Endgame directors the Russo brothers threw up a blurry image of the words “Doomsday Is Coming.”

That movie concluded with Robert Downey Jr.’s Doctor Doom and Franklin Richards and indications of a plotline which could carryover directly into the events of Avengers: Doomsday.
The teaser has fans divided: Some are hoping for a trailer release soon, while others think it indicates undisclosed cast members — or even the un-dead Chris Evans’ Steve Rogers. At the same time, Ryan Reynolds, himself, has teased his MCU connections on social media, only serving to fan the flames further.
The X-Men, the Fantastic Four and the Doctor Doom Factor
Work has started on Avengers: Doomsday and Channing Tatum is back as Gambit after his Deadpool & Wolverine cameo.He has teased a major fight with Doctor Doom, suggesting that the X-Men will play a significant role in the movie.
With the New Avengers, classic Avengers, Fantastic Four, and X-Men all expected to unite, fans are eager to know how Doctor Strange might fit into the narrative. His knowledge of incursions and multiverses makes him a crucial character for connecting Doomsday to Avengers: Secret Wars (2027).
What’s Next for Doctor Strange and the MCU?
Marvel has an untitled film set for July 2027, positioned between Avengers: Doomsday and Avengers: Secret Wars. Many speculate this could be Doctor Strange 3, potentially explaining his uncertain status and bridging the two Avengers installments.
For now, Marvel has not confirmed whether Benedict Cumberbatch will appear in Doomsday. But between the Russo Brothers’ teaser, the mysterious cast list, and returning actors, the film is already one of the most highly anticipated Marvel releases in years.
