Though Downey Jr. takes on a new part, Marvel is essentially reuniting its ensembles here. The story unfolds 14 months after the events of this year’s Thunderbolts*. That brings back Avengers staples like Thor (Chris Hemsworth), the current Captain America (Anthony Mackie), Bucky Barnes (Sebastian Stan), Ant-Man (Paul Rudd), Falcon (Danny Ramirez), and Loki (Tom Hiddleston). On the Wakandan side there’s Shuri as the new Black Panther (Letitia Wright), M’Baku (Winston Duke), and Namor (Tenoch Huerta Mejia).
Of course the Thunderbolts* (aka New Avengers) show up: John Walker/US Agent (Wyatt Russell), Yelena Belova (Florence Pugh), Bob/Sentry (Lewis Pullman), Red Guardian (David Harbour), and Ghost (Hannah John-Kamen). The Fantastic Four are on hand as well: Reed Richards (Pedro Pascal), Sue Storm (Vanessa Kirby), Ben Grimm (Ebon Moss-Bachrach), and Johnny Storm (Joseph Quinn). The original X-Men also return: Charles Xavier (Patrick Stewart), Beast (Kelsey Grammer), Magneto (Ian McKellen), Mystique (Rebecca Romijn), Nightcrawler (Alan Cumming), and Cyclops (James Marsden).
Marvel also adds Gambit (Channing Tatum) and Xu Shang-Chi (Simu Liu) for good measure. Expect numerous cameos, including a recently revealed Steve Rogers appearance. We can likely spot (at least briefly) Peggy Carter, Spider-Man (Tom Holland), Hawkeye (Jeremy Renner), and Doctor Strange (Benedict Cumberbatch), among others.
Avengers: Doomsday opens in theaters on December 18, 2026. Avengers: Secret Wars is scheduled for release on December 17, 2027, and will mark the conclusion of the MCU’s Phase Six.
