Avengers: Doomsday releases in cinemas on December 18, 2026, in India and worldwide, and it is already shaping up as the biggest film event since Endgame. The reason sits right at the top of the poster: Robert Downey Jr is back in the Marvel universe, not as Iron Man, but as its new villain, Doctor Doom. This page is your single tracker for the release date, cast and every official update between now and December.
The essentials first. The film is directed by Joe and Anthony Russo, the pair behind Infinity War and Endgame, with Stephen McFeely writing. The first full trailer premiered in July and advance ticket sales have already opened in several markets, months ahead of release, something studios only do when they expect a stampede.
The confirmed cast is the largest Marvel has ever assembled. Alongside Downey’s Doom: Chris Hemsworth as Thor, Anthony Mackie as Captain America, Tom Hiddleston as Loki, Florence Pugh as Yelena, Sebastian Stan, Paul Rudd, Simu Liu, Letitia Wright and Winston Duke. The new Fantastic Four, Pedro Pascal, Vanessa Kirby, Ebon Moss-Bachrach and Joseph Quinn, walk straight in from First Steps. And the headline shock: the original X-Men are here, with Patrick Stewart, Ian McKellen, Kelsey Grammer, James Marsden, Rebecca Romijn and Alan Cumming returning, plus Channing Tatum’s Gambit.
What the trailer tells us: Doom speaks with a Latverian accent, refers to an unthinkable decision, and commands an army of Sentinels, the mutant hunting machines X-Men fans know all too well. The film sets up Doom discovering the multiverse and eyeing other realities to rule, leading directly into Avengers: Secret Wars.
For viewers in India and Pakistan: expect the usual Marvel rollout, English plus Hindi, Tamil and Telugu dubs in cinemas, with IMAX bookings opening closer to release. The OTT release will follow the theatrical run months later, and once it is announced, we will track it the way we track every big premiere.
Between now and December this page updates with every trailer, booking date and confirmation. For what to watch first, our guide to the essential films before Doomsday goes up right after this one.
