Avengers: Doomsday (2026)
About
Avengers: Doomsday is the fifth Avengers film and the first since Avengers: Endgame (2019). Anthony Russo and Joe Russo return to direct, and Robert Downey Jr., who played Tony Stark for eleven years, comes back to the Marvel Cinematic Universe as a different character: the villain Victor von Doom.
Plot
Marvel has kept the story under wraps. The official outline says that heroes from three different universes are heading for a collision, and that together they face a threat to the whole Multiverse. That threat is Doctor Doom (Downey). A tie-in book synopsis released in November 2026 says the Avengers, the New Avengers (the team formed at the end of Thunderbolts*), the Wakandans, the Fantastic Four and the X-Men have to put aside their distrust of one another to stop him, and that the teams do not get on easily. The film is set about fourteen months after Thunderbolts* (2025), and the end-credits scene of The Fantastic Four: First Steps (2025) leads into it.
Where it fits in the series
Doomsday belongs to Phase Six of the Marvel Cinematic Universe and is the first half of a two-part story that ends with Avengers: Secret Wars, due on December 17, 2027. It brings together characters who have never shared a screen in the MCU: the Avengers led by Sam Wilson's Captain America, Thor, the Thunderbolts, Wakanda's Shuri and M'Baku, the Fantastic Four from First Steps, and the X-Men of the original Fox films, with Patrick Stewart, Ian McKellen, James Marsden, Rebecca Romijn, Alan Cumming and Kelsey Grammer back in their roles. Chris Evans also returns as Steve Rogers, who retired at the end of Endgame.
Production
Marvel first announced the film in July 2022 as Avengers: The Kang Dynasty, with Destin Daniel Cretton directing and Jeff Loveness writing, and Jonathan Majors's Kang as the villain. Cretton left in November 2023, Michael Waldron took over the script, and Majors was dropped by Marvel the following month. At San Diego Comic-Con in July 2024 the Russo brothers were confirmed as directors of both remaining Avengers films, the first was retitled Doomsday, and Downey was unveiled as Doom. The screenplay is by Stephen McFeely, who co-wrote Infinity War and Endgame, and Waldron. A cast announcement was livestreamed on March 26, 2025, revealing names one chair at a time.
Filming ran from April to September 2025, based at Pinewood Studios in England. The release was pushed back to May 1, 2026 and then again to December 18, 2026. Kevin Feige produces, Alan Silvestri, who scored The Avengers, Infinity War and Endgame, returns as composer, and the reported running time is about 165 minutes. Disney re-released Endgame on Disney+ as Avengers: Endgame Encore on November 13, 2026, ahead of the new film.
