Marvel is bringing Avengers: Endgame back to cinemas under a new title: Avengers: Endgame Encore. The re-release begins September 25, 2026, ahead of Avengers: Doomsday on December 18. Disney says tickets are available for IMAX and Infinity Vision-certified screens, with the presentation built around a new introduction, additional footage and a special end tag.

The biggest confirmed detail is the runtime: AMC listings put Endgame Encore at 185 minutes, compared with 181 minutes for the original 2019 theatrical cut. That makes the new version approximately four minutes longer and, based on the listing, the longest Marvel Studios theatrical release to date.

What is new in Endgame Encore?
Disney and exhibitors have confirmed three additions:
- a custom introduction;
- additional new footage; and
- a special end tag connected to Avengers: Doomsday.

The 185-minute listing indicates that the total added material is roughly four minutes compared with the original cut. However, Marvel has not publicly itemized the scenes, so claims about precisely what happens in the new footage remain unconfirmed.

The marketing promises an “exclusive look” at Avengers: Doomsday. Reports describe the new material as a bridge to the next Avengers film, but the available announcement does not establish that all four additional minutes consist of previously unseen Doomsday footage.

Which version will play in theaters?
The newly announced material is tied to premium formats. Disney specifically lists IMAX and Infinity Vision-certified screens for the re-release, while reporting says the custom introduction, added footage and end tag are exclusive to those formats. Standard screenings are expected to show the original 2019 presentation rather than the complete Encore package.

That makes the screen format an important part of the ticket decision: seeing the film in a conventional auditorium may not provide the same newly added material as an IMAX or Infinity Vision screening.
What is Infinity Vision?
Infinity Vision is Disney’s new certification for Premium Large Format cinemas. Disney describes the program as a guarantee of a large-screen presentation with bright images and strong sound. Endgame Encore is being used to introduce the certification to MCU audiences before Avengers: Doomsday arrives.

The sources do not confirm that the program was created specifically as a response to Dune: Part Three or its reported IMAX commitment. That explanation remains industry speculation rather than an announced Disney rationale.
How does Tony Stark fit into the promotion?
The re-release also arrives as Marvel revisits the creative decision that ended Tony Stark’s story. Joe Russo has said the filmmakers debated how to conclude Stark’s arc and ultimately viewed his death as the boldest choice.

Robert Downey Jr. is returning to the MCU in Avengers: Doomsday as Victor von Doom, also known as Doctor Doom—not as Tony Stark or Iron Man. That casting makes the transition from Endgame to Doomsday especially significant, even though Marvel has not explained how the new Encore material will handle the connection.

Does Endgame Encore threaten the box-office records?
The re-release is being positioned as an event screening, but its eventual box-office impact cannot be known before release. The film is already available on Disney+, and the sources do not provide a reliable forecast for how much additional theatrical revenue the new presentation will generate.
Spider-Man: Brand New Day did set a reported $360 million domestic opening-weekend record, surpassing Avengers: Endgame’s previous $357 million benchmark.

37 That opening-weekend comparison is separate from total domestic grosses: later tracking listed Brand New Day at roughly $855 million domestically against Endgame’s $858.3 million total, while another database subsequently listed Brand New Day at $858.4 million.

The clearest takeaway is therefore not a guaranteed record comeback. Endgame Encore is a limited, premium-format return designed to add a small amount of new material and build anticipation for Avengers: Doomsday—with the most important details still being held back.
