Since “Avengers: Endgame,” many of the main heroes from previous films have retired or died, and new characters have been introduced to the MCU through various films and Disney+ shows.
In March 2025, Marvel confirmed that “Avengers: Doomsday” is now in production. The studio also announced a slew of “Avengers: Doomsday” cast members via an hourslong livestream.
In addition to Downey Jr., many other major MCU stars will be back: Chris Hemsworth (Thor), Tom Hiddleston (Loki), Paul Rudd (Scott Lang/Ant-Man), and Simu Liu (Shaun/Shang-Chi).
Anthony Mackie (Sam Wilson/Captain America) and Danny Ramirez (Joaquin Torres/Falcon), who most recently reprised their Marvel roles in “Captain America: Brave New World,” will return in “Doomsday.”
Additionally, the movie will include actors who will star in Marvel’s next two films set for release this year, “Thunderbolts*” and “The Fantastic Four: First Steps.”
“Thunderbolts”*,” set for release on May 2, centers on a ragtag group of assassins and spies who’ve already appeared in previous MCU projects and must work together on a mission.
Cast members Sebastian Stan (Bucky Barnes/Winter Soldier), Wyatt Russell (John Walker/US Agent), Florence Pugh (Yelena Belova), David Harbour (Alexei Shostakov/Red Guardian), Hannah John-Kamen (Ava Starr/Ghost), and Lewis Pullman (Bob/Sentry) will return in “Doomsday.”
After making their MCU debuts this summer in “Fantastic Four,” Pedro Pascal (Reed Richards/Mr. Fantastic), Vanessa Kirby (Sue Storm/Invisible Woman), Joseph Quinn (Johnny Storm/Human Torch), and Ebon Moss-Bachrach (Ben Grimm/The Thing) will reprise their roles for “Doomsday.”
The “Avengers” movie will feature “Black Panther: Wakanda Forever” stars Letitia Wright (Shuri/Black Panther), Tenoch Huerta Mejía (Namor), and Winston Duke (M’Baku).
“X-Men” actor Kelsey Grammer will also appear in the film, likely reprising his role as Hank McCoy/Beast after his appearance in the end-credits scene of “The Marvels.”
He’s not the only “X-Men” alum who will be part of “Doomsday.” The cast list includes Patrick Stewart (Charles Xavier/Professor X), Ian McKellen (Erik Lehnsherr/Magneto), Alan Cumming (Kurt Wagner/Nightcrawler), Rebecca Romijn (Raven Darkholme/Mystique), and James Marsden (Scott Summers/Cyclops).
Fans of Channing Tatum’s performance as Gambit in “Deadpool & Wolverine” will also rejoice in the news that he’ll appear in “Doomsday.”
The list of 27 cast members noticeably excludes major MCU stars like Mark Ruffalo (Bruce Banner/Hulk), Jeremy Renner (Hawkeye), Benedict Cumberbatch (Stephen Strange/Doctor Strange), Tom Holland (Peter Parker/Spider-Man), Brie Larson (Carol Danvers/Captain Marvel), and Elizabeth Olsen (Wanda Maximoff/Scarlett Witch).
It’s likely that additional “Doomsday” actors will be announced at a later date.
