There is a question circulating among Marvel fans about why Marvel hasn’t announced the full cast details for Avengers: Doomsday during the live-streamed cast announcement. As of now, only 27 cast members have been officially announced.
According to insider Daniel Richtman, Marvel Studios only revealed some names for Avengers: Doomsday because they wanted a bigger reveal when filming begins. Also, not all deals are finalized yet, so they only confirmed the actors who are officially signed on.

In a recent interview with The Hollywood Reporter, the Russo Brothers revealed that Marvel gave them baseball cards to track MCU actors and their contracts.
Anthony Russo said, “Yes, we continue to use the baseball cards.”
Joe Russo added, “Now they have magnets on them so we can put ‘em on a board and look at ‘em. It’s the only way to keep track of the number of characters we’re working with [in these two films].”
The film stars Robert Downey Jr. as Doctor Doom, Paul Rudd as Ant-Man, Simu Liu as Shang-Chi, Tom Hiddleston as Loki, Florence Pugh as Yelena Belova, Danny Ramirez as Falcon, Sebastian Stan as Bucky Barnes, Winston Duke as M’Baku, Chris Hemsworth as Thor, Letitia Wright as Black Panther, Tenoch Huerta Mejía as Namor, Anthony Mackie as Captain America, David Harbour as Red Guardian, Wyatt Russell as U.S. Agent, and Hannah John-Kamen as Ghost. Ian McKellen as Magneto, Patrick Stewart as Professor X, Rebecca Romijn as Mystique, James Marsden as Cyclops, Kelsey Grammer as Beast, Alan Cumming as Nightcrawler, and Channing Tatum as Gambit. Pedro Pascal as Reed Richards (Mr. Fantastic), Vanessa Kirby as Sue Storm (Invisible Woman), Joseph Quinn as Johnny Storm (Human Torch), Ebon Moss-Bachrach as Ben Grimm (The Thing), and Lewis Pullman as Sentry.

Jackson as Nick Fury, Hailee Steinfeld as Kate Bishop, Elizabeth Olsen as Scarlet Witch, Dakota Johnson as Madame Web, Xochitl Gomez as America Chavez, Teyonah Parris as Monica Rambeau, and Benedict Cumberbatch as Doctor Strange.

Production for Doomsday is now underway in the United Kingdom. The film will mark the beginning of the end of the Marvel Cinematic Universe (MCU). As the multiverse nears total collapse, the Avengers must assemble to face their biggest challenge yet—incursions, catastrophic collisions between realities that could destroy the entire multiverse. Earth’s Mightiest Heroes must race against time to save their reality while confronting the powerful figure behind it all—Victor Von Doom (Downey Jr.).
Produced by Kevin Feige, Louis D’Esposito, and Russo Brothers will produce through their AGBO banner.
Avengers: Doomsday will hit theaters on May 1, 2026.
