The Avengers: Endgame re-release arrives in theaters on September 25, 2026, retitled Avengers: Endgame Encore. It adds a custom introduction, new footage, and a special end tag — but that new material is exclusive to IMAX and Disney’s new Infinity Vision format, not standard screens. It lands twelve weeks before Avengers: Doomsday.
That exclusivity clause is not a footnote. It is the entire reason this re-release exists, and it tells you something about what Disney is really doing this fall.
Avengers: Endgame Encore release date and what’s new
Marvel Studios announced the return during its San Diego Comic-Con 2026 presentation, with Joe and Anthony Russo confirming that the re-release would not be a straight replay of the 2019 cut.
Here is what has actually been confirmed:
| Detail | Confirmed |
|---|---|
| Release date | September 25, 2026 |
| New title | Avengers: Endgame Encore |
| Custom introduction | Yes — premium formats only |
| Additional footage | Yes — premium formats only |
| Special end tag | Yes — premium formats only |
| Formats with new material | Infinity Vision and IMAX |
| Final runtime | Not officially confirmed |
| Leads into | Avengers: Doomsday, December 18, 2026 |
Reports following the announcement have suggested the new cut runs several minutes longer than the original three-hour-plus film, but Marvel has not published an official runtime, so treat specific numbers as unconfirmed for now.
What is Infinity Vision?
Infinity Vision is Disney’s own premium large-format theatrical standard — its answer to IMAX and Dolby Cinema. Rather than licensing a third-party format for its biggest releases, Disney is building a certified network of theaters under its own banner.
Participating venues are “Infinity Vision certified,” and per reporting on the announcement, the new Endgame Encore material will only play in those certified rooms and in IMAX.
The real strategy: this is a format launch, not a victory lap
Strip away the nostalgia and look at the mechanics.
Disney has a new proprietary premium format that needs two things to succeed: exhibitors willing to pay for certification, and audiences trained to seek the format out by name. Both are hard to bootstrap. Premium formats live or die on whether the public believes the upcharge is worth it — and you cannot establish that with a mid-tier release.
So Disney reached for the most rewatched, most emotionally loaded film in its catalogue, and made the only version with new content format-exclusive. That is a remarkably efficient piece of leverage:
- Exhibitors get a certification incentive. A theater without Infinity Vision cannot sell the complete version of the most beloved MCU film. That is a concrete argument for upgrading, three months before the biggest release of the year.
- Audiences get trained on the name. Fans who want the new end tag have to actively search for an Infinity Vision showtime. That search behavior is the whole point.
- Doomsday inherits an installed base. By December 18, the format has a proven audience and a certified theater footprint — built at the cost of re-mastering a film Disney already owns.
In other words: the re-release is not the product. The format is the product, and Endgame is the delivery mechanism.
The problem this creates
There is a real cost to that strategy, and it is worth naming.
If the special end tag genuinely sets up Avengers: Doomsday — and every signal suggests it does — then Marvel has created a two-tier canon. Viewers in a standard auditorium will watch the same film they saw in 2019 and walk out without the setup. Viewers who live near a certified premium screen, and who can afford the premium ticket, get the connective tissue.
Marvel has historically been careful about this. Post-credits stingers ran on every screen, in every format, at the same price. Gating story-relevant material behind a format upcharge is a meaningful departure — and if Doomsday opens in December assuming you saw that tag, a lot of casual viewers are going to be missing a beat they did not know existed.
Whether that matters depends entirely on how load-bearing the new footage turns out to be. A mood-setting introduction is fine. A tag that introduces a character or explains Doom’s arrival is a different conversation.
How Endgame Encore fits the road to Doomsday
Avengers: Doomsday arrives December 18, 2026, with Robert Downey Jr. returning as Doctor Doom. A September re-release places Endgame in theaters at almost exactly the twelve-week mark — long enough for the buzz to compound, close enough that the emotional groundwork is fresh.
It also arrives into an unusually hot theatrical market. Spider-Man: Brand New Day has just posted the biggest opening in box office history, which means Marvel goes into the fall with maximum audience goodwill and exhibitors highly motivated to say yes to whatever Disney asks for. The timing on the format push is not accidental.

Frequently asked questions
When is the Avengers: Endgame re-release?
Avengers: Endgame Encore returns to theaters on September 25, 2026, approximately twelve weeks before Avengers: Doomsday opens on December 18, 2026.
Does the Endgame re-release have new footage?
Yes. The re-release includes a custom introduction, additional footage, and a special end tag. However, that new material is exclusive to IMAX and Infinity Vision certified screenings — standard auditoriums are not confirmed to receive it.
Why is Endgame being retitled “Encore”?
Disney is retitling the film Avengers: Endgame Encore to distinguish the 2026 theatrical version, which contains new material, from the original 2019 release. The retitle also gives the re-release its own identity for ticketing and marketing.
What is Infinity Vision?
Infinity Vision is Disney’s proprietary premium large-format theatrical standard, positioned as a competitor to IMAX and Dolby Cinema. Theaters must be certified to present it, and the exclusive Endgame Encore material is limited to those certified screens and IMAX.
The bottom line
If you want the complete Endgame Encore, you need an IMAX or Infinity Vision ticket — a standard screening will give you the 2019 film. Book early for opening weekend on September 25, because certified screens will be a limited pool by design. That scarcity is the strategy, not an accident. More detail is available via Marvel’s official announcement and Variety’s report on the new footage.
