Why it matters

The biggest reset Marvel has attempted since Endgame, with the Russo brothers back and Robert Downey Jr. returning as a different character entirely.

About Avengers: Doomsday

Seven years after Endgame closed one era of the Marvel Cinematic Universe, Avengers: Doomsday opens the next. Anthony and Joe Russo return to direct, with Stephen McFeely and Michael Waldron writing, and the central casting decision is Robert Downey Jr. coming back to the franchise not as Tony Stark but as Doctor Doom. The film pulls characters out of separate corners of the series and into one story, which is how Marvel Studios is finally paying off the multiverse idea it has been assembling since 2021.

Disney opens it on December 18, 2026, moved from an original May 2026 slot, with Avengers: Secret Wars following in December 2027 as the second half of the pair. Marvel has kept the plot locked down, and the first real look at Downey's Doom came at CinemaCon. What is clear is the size of the bet: two Avengers films a year apart, both from the Russos, meant to reset a series whose box office has been uneven since 2019. Worth knowing going in, this is the setup rather than the payoff.
