The Marvel Cinematic Universe is set to undergo a seismic shift with Avengers: Doomsday, officially confirmed to be in production. In a grand reveal, the film’s star-studded cast was announced during a livestream event, generating immense excitement among fans. The upcoming installment not only unites MCU’s most beloved heroes but also marks a spectacular X-Men reunion, featuring legendary actors Patrick Stewart, Ian McKellen, Alan Cumming, Rebecca Romijn, and Kelsey Grammer. Adding to the excitement, Robert Downey Jr. makes his highly anticipated return to the Marvel universe as Victor von Doom, a.k.a. Doctor Doom.
An Unparalleled Casting Reveal
Marvel Studios unveiled the Avengers: Doomsday cast in a slow-burning livestream video, where actors’ chairs were revealed one by one. The event kicked off with familiar faces, including Chris Hemsworth (Thor), Paul Rudd (Ant-Man), Anthony Mackie (Sam Wilson/Captain America), Sebastian Stan (Bucky Barnes/Winter Soldier), Letitia Wright (Shuri/Black Panther), Wyatt Russell (John Walker/U.S. Agent), Tenoch Huerta Mejia (Namor), and Ebon Moss-Bachrach (Ben Grimm/The Thing).
As the stream continued, more names emerged: Simu Liu (Shang-Chi), Florence Pugh (Yelena Belova), Kelsey Grammer (Beast/Hank McCoy), Danny Ramirez (Joaquin Torres/Falcon), Joseph Quinn (Johnny Storm/Human Torch), Pedro Pascal (Reed Richards/Mister Fantastic), David Harbour (Red Guardian), Winston Duke (M’Baku), Hannah John-Kamen (Ava Starr/Ghost), and Tom Hiddleston (Loki).
However, the final hour delivered the biggest bombshells. Patrick Stewart (Professor X), Ian McKellen (Magneto), Alan Cumming (Nightcrawler), Rebecca Romijn (Mystique), and James Marsden (Cyclops) joined fellow X-Men alum Kelsey Grammer, cementing this film as a massive Marvel crossover. To top it off, Channing Tatum was officially confirmed to reprise his long-anticipated role as Gambit, first introduced in Deadpool & Wolverine.
The climactic moment of the event saw Robert Downey Jr. walking down the set, taking his place in the final chair. Moments later, the screen displayed, Avengers: Doomsday now in production.
The X-Men’s Long-Awaited MCU Integration
With Disney’s acquisition of 20th Century Fox, Marvel Studios has gradually integrated X-Men characters into the MCU. Stewart’s Xavier made his debut in Doctor Strange in the Multiverse of Madness, followed by Grammer’s Beast in The Marvels.
Now, Avengers: Doomsday is set to be the defining moment that fully brings the X-Men into the MCU fold. This not only bridges the gap between past and present Marvel franchises but also sets the stage for the upcoming Avengers: Secret Wars, which is expected to explore even more multiversal madness.
The Bigger Picture – A Universe Expanding
Several characters in Avengers: Doomsday are yet to make their full debuts. Vanessa Kirby, Ebon Moss-Bachrach, Pedro Pascal, and Joseph Quinn will first appear as the Fantastic Four in The Fantastic Four: First Steps (July 25, 2025). Meanwhile, Danny Ramirez and Anthony Mackie have already taken flight in Captain America: Brave New World earlier this year.
Additionally, Thunderbolts (May 2, 2025) will showcase key players like Florence Pugh, Wyatt Russell, Sebastian Stan, David Harbour, and Hannah John-Kamen. As speculation grows, fans are particularly intrigued by Lewis Pullman’s mysterious character “Bob,” rumored to be The Sentry.
Marvel Studios President Kevin Feige confirmed that Avengers: Secret Wars—the direct sequel to Doomsday—will further delve into mutant lore. According to Feige, “This phase of Marvel leads us into a new age of mutants and the X-Men.”
Marvel’s Next Big Blockbusters
Avengers: Doomsday, helmed by Joe and Anthony Russo—directors of Avengers: Infinity War and Endgame—will hit theaters on May 1, 2026. It will be followed by Avengers: Secret Wars, scheduled for May 7, 2027.
With a powerhouse cast, a long-awaited X-Men integration, and the return of Robert Downey Jr., Avengers: Doomsday is shaping up to be one of the most ambitious Marvel films to date. The countdown has begun, and the future of the MCU has never looked more exciting.
