Quick Answer
Avengers: Endgame returns to theaters on Friday, September 25, 2026, in a re-release that includes new footage. Marvel Studios announced the date in a December 2025 newsroom post; the new footage was confirmed by directors Joe and Anthony Russo at the Walt Disney Studios CinemaCon 2026 presentation in April.
The re-release lands roughly twelve weeks before Avengers: Doomsday, which is scheduled for December 18, 2026, and is positioned as a primer for audiences who want to revisit the end of the Infinity Saga before the start of the next team-up film.
The official re-release date and theaters
The September 25, 2026 release was first announced on Marvel.com on December 5, 2025, and confirmed by The Hollywood Reporter and IGN the same day. Disney has not publicly disclosed the length of the theatrical window, but precedent (the 2024 re-release of Star Wars: The Phantom Menace ran for two weeks) suggests a roughly two to three week run before the film moves back to Disney+.
At CinemaCon 2026, Disney also unveiled Infinity Vision, a new premium large format certification for select cinemas. The Endgame re-release is one of the first films to be marketed under that banner, alongside the upcoming Doomsday.
What is the new footage?
Speaking on stage at CinemaCon, Joe and Anthony Russo confirmed that the re-release will include new footage that was not in the 2019 theatrical cut. They declined to describe what the footage shows or where in the film it appears.
Variety, IGN and MovieWeb all reported the announcement and noted that the brothers framed the addition as a bridge to Doomsday rather than an extended cut of existing scenes. Industry analysts have speculated the footage may sit in the post-credits, or take the form of a new sequence involving the Time Variance Authority, which would link the events of Endgame's time heist to the multiversal threat in Doomsday. Marvel has not confirmed any of this.
Why Marvel is re-releasing Endgame now
Three reasons are driving the re-release:
- Refresh the audience. Endgame opened in April 2019. A significant share of the moviegoing audience under 25 has not seen it on a big screen, and many older fans have not watched it in years. Doomsday is heavily dependent on Endgame's emotional and narrative beats (Tony Stark's death, the snap reversal, the Avengers Tower aftermath), and Marvel wants those moments fresh in viewers' minds.
- Establish multiversal continuity. The Multiverse Saga has expanded into Loki, Deadpool and Wolverine, Quantumania and several Disney+ series. By inserting new footage into Endgame, Marvel can retroactively plant a thread that pays off in Doomsday without having to deliver another exposition heavy Phase film.
- Box office momentum. The 2024 re-release of Star Wars: The Phantom Menace earned roughly 14 million dollars domestically. Endgame is the second highest grossing film in history (2.799 billion dollars globally before the re-release), and even a modest re-release week will generate strong returns, plus a sizable bump for Doomsday previews shown before the screening.
How the re-release fits the road to Avengers: Doomsday
Avengers: Doomsday is scheduled for December 18, 2026, and is also directed by Joe and Anthony Russo. The film is widely reported to feature Robert Downey Jr. in a new role as Doctor Doom, the main antagonist, alongside a large ensemble of returning MCU characters. The exact cast list has not been fully confirmed by Marvel.
Marvel's release calendar between September and December 2026 keeps the runway clear of other in-house tentpoles, which suggests the studio is treating the Endgame re-release as the de facto trailer campaign for Doomsday. Expect a new Doomsday trailer to drop with the Endgame re-release, and likely an exclusive Doomsday teaser scene attached to the print.
Should you see the re-release in theaters?
If you have never seen Endgame on a big screen, yes. Even the 2019 theatrical experience now feels like a cultural event in retrospect, and the Infinity Vision presentation in select cinemas will offer better picture and sound than any home setup short of a high end home theater.
If you saw it in 2019 and have rewatched it on Disney+ since, the calculus comes down to the new footage and the Doomsday tie-in material that will likely play before or after the feature. For most fans planning to see Doomsday in December, the re-release is worth the ticket as a refresher and as a chance to see whatever new sequence the Russos have inserted before it leaks online.
The takeaway
Avengers: Endgame returns to theaters on September 25, 2026, with new footage confirmed by the Russo brothers at CinemaCon 2026. The re-release is the first major release under the new Infinity Vision premium format and is timed as a deliberate runway to Avengers: Doomsday on December 18, 2026. For fans, it is the easiest way to refresh the Infinity Saga before Doomsday lands; for Marvel, it is a low risk box office bump that doubles as the Doomsday marketing campaign.
