Marvel Studios is set to re-release Avengers: Endgame, its 2019 blockbuster, on September 25, 2026—three months before the release of Avengers: Doomsday. This re-release comes as part of the Multiverse Saga, a series of films and shows that began in 2021 and follows the Infinity Saga (2008–2019), which included 23 interconnected films starting with Iron Man (2008). The Multiverse Saga has introduced new characters like Moon Knight and Ironheart, as well as expanded the Marvel Cinematic Universe (MCU) through television series that add depth to its storylines. Avengers: Endgame was the climax of the Infinity Saga and remains the highest-grossing film in history. It also holds a 94% "fresh" rating on Rotten Tomatoes, a review aggregator that measures audience and critic reception. The film, starring Robert Downey Jr. as Iron Man, was pivotal in saving Marvel from financial trouble and is widely considered a cultural milestone in cinema. However, recent films in the Multiverse Saga, such as The Eternals (2021), Thunderbolts (2025), and Captain America: Brave New World (2025), have not performed as well at the box office. Some fans have compared following the saga to "doing chores" or "doing homework," suggesting a shift in how audiences engage with the MCU. Instead of following every interconnected storyline, fans now tend to focus on a few favorite characters or plots. The re-release of Avengers: Endgame may signal Marvel’s response to these challenges. The new version will include additional footage that connects Endgame to Doomsday, skipping over recent developments in the Multiverse Saga. Robert Downey Jr., who portrayed Iron Man, is also set to play Dr. Doom, the main antagonist in Doomsday. Notably, several characters from the Multiverse Saga will not appear in Doomsday, hinting at a possible reset of the MCU. This could be similar to comic book events like Crisis on Infinite Earths, where the existing universe was rewritten. While it remains uncertain whether Doomsday will lead to a full reset, the re-release of Endgame aims to reestablish the narrative and relationships that made the original saga a success.
