Avengers: Endgame is the second-highest-grossing film of all time, and Disney is intending to rerelease it in theatres on September 25, 2026, for a special engagement. Releasing on December 18, 2026, Avengers: Doomsday is the next big team-up film, and the 2019 blockbuster will serve as a huge cinematic "pre-game" event preceding it.
Strategic scheduling and MCU momentum
The rerelease of Endgame is carefully scheduled to coincide with other MCU events. There will be a flurry of high-profile releases in late 2026, beginning with Spider-Man: Brand New Day on July 31, with the intention of building tremendous momentum leading up to the Christmas season's anchor film, Doomsday.
Upon its initial release in April 2019, Endgame became an instant hit and broke multiple box office records. The film's stunning $1.9 billion haul in its opening weekend made it the largest opening weekend globally. Its worldwide box office total of almost $2.7 billion is second only to James Cameron's Avatar ($2.9 billion) in all-time earnings. In anticipation of the new saga, the forthcoming rerelease is sure to attract audiences old and new.
Robert Downey Jr. as Doctor Doom
It has been revealed that Joe and Anthony Russo, who directed the original Endgame, will be directing Doomsday. The stunning casting revelation that Robert Downey Jr, who played Tony Stark/Iron Man for more than ten years, will be returning to Marvel films has stoked significant interest in their involvement. But Downey Jr will not be returning to play Stark. He has instead decided to assume the role of Doctor Doom, the legendary supervillain.
In honour of the Endgame rerelease announcement, the production firm owned by the Russo brothers, AGBO Films, shared a video on social media showing the enthusiastic and thunderous reactions of viewers to the film's final assembly scene. Words like "You remember this feeling. You love this feeling. So do we" was superimposed on the video cut. Titling the video, AGBO added: "The greatest pre-game for Avengers: Doomsday is the Endgame." The addition further solidified the scheme.
Massive roster and collision of Universes in Doomsday
Coming back for Avengers: Doomsday is a diverse and large cast of heroes. Cast members who have been confirmed include:
Chris Hemsworth as Thor.
Anthony Mackie as Sam Wilson, the new Captain America.
Sebastian Stan as Bucky Barnes/Winter Soldier.
Paul Rudd as Scott Lang/Ant-Man.
Tom Hiddleston as Loki.
Letitia Wright portrayed Shuri, who assumed the Black Panther mantle in Wakanda Forever.
Winston Duke as M’Baku.
Marvel Cinematic Universe regulars like these will be joined by superhero teams from other upcoming films like Thunderbolts* and The Fantastic Four: First Steps in this film. Also, Marvel's film universes are about to collide in a massive way, with the addition of X-Men characters like Professor Charles Xavier (Patrick Stewart) and Magneto (Ian McKellen) to Doomsday.
