Avengers Doomsday Cast Announcement: Full List of Marvel Stars Revealed!

The highly anticipated Avengers: Doomsday cast announcement has finally dropped, sending Marvel fans into a frenzy.

Marvel Studios kicked off production for the film, set to release on May 1, 2026, with a nearly five-and-a-half-hour livestream that unveiled a star-studded lineup.

From returning MCU veterans to iconic X-Men actors, the cast promises an epic showdown led by Robert Downey Jr. as the villainous Doctor Doom.

What Is Avengers: Doomsday About?

Marvel Studios announced Avengers: Doomsday at San Diego Comic-Con in July 2024.

The film marks the return of Robert Downey Jr. to the MCU, this time as Doctor Doom, after his iconic run as Iron Man ended with Avengers: Endgame.

Directed by the Russo brothers, who previously helmed Infinity War and Endgame, the movie is the first of a two-part saga, with Avengers: Secret Wars following on May 7, 2027.

Who Are the Directors Behind Avengers: Doomsday?

Anthony and Joe Russo are directing both Avengers: Doomsday and Avengers: Secret Wars. The duo revealed they use baseball cards with magnets to keep track of the massive roster of characters, a method they also employed during Infinity War and Endgame.

Joe Russo noted the challenge of managing so many characters, while Anthony emphasized the creative process of selecting characters to push the story into surprising directions.

Which MCU Veterans Are Returning for Avengers: Doomsday?

The cast includes several MCU mainstays. Chris Hemsworth returns as Thor, joined by Tom Hiddleston as Loki and Anthony Mackie as the new Captain America. Paul Rudd reprises his role as Ant-Man, while Letitia Wright continues as Black Panther.

Simu Liu (Shang-Chi), Danny Ramirez (The Falcon), and Winston Duke (M’Baku) are also confirmed. The Thunderbolts cast, including Sebastian Stan (The Winter Soldier), Florence Pugh (Yelena Belova), and Wyatt Russell (U.S. Agent), will also appear.

Which X-Men Stars Are Joining the Avengers: Doomsday Cast?

A major highlight is the inclusion of X-Men actors from the Fox universe. Patrick Stewart returns as Professor X, alongside Ian McKellen as Magneto. Other X-Men stars include Alan Cumming (Nightcrawler), Rebecca Romijn (Mystique), and James Marsden (Cyclops).

Ariana Grande is set to play a variant of Professor X, a role teased in her short film Eternal Sunshine: Brighter Days Ahead, where she used the X-Men’s Cerebro.

Who Are the New Additions to the Avengers: Doomsday Cast?

Channing Tatum will officially reprise his role as Gambit, following his appearance in Deadpool & Wolverine. Vanessa Kirby joins as Sue Storm (Invisible Woman) from the upcoming Fantastic Four: First Steps.

These additions signal Marvel’s intent to blend characters from various franchises into the MCU’s Multiverse Saga.

Why Is Spider-Man Missing from Avengers: Doomsday?

Tom Holland’s Spider-Man is notably absent from the cast. Reports suggest Spider-Man 4, set to release in July 2026, takes place during the events of Avengers: Doomsday, explaining his absence.

Holland is also busy filming Christopher Nolan’s The Odyssey, which began production in February 2025. Fans speculate this allows Peter Parker’s solo story to develop further before rejoining the Avengers.

What Was the Impact of the Avengers: Doomsday Cast Announcement Livestream?

The cast announcement livestream garnered 275 million digital views, making it Marvel’s most-viewed livestream ever, according to Deadline. It featured 27 director’s chairs revealed over five hours, each with a star’s name, accompanied by music from their respective Marvel films.

The event concluded with Robert Downey Jr. giving a “shhh” gesture, teasing more surprises to come.
