Marvel is bringing Avengers: Endgame back to theaters this September, but Avengers: Endgame Encore appears to be carrying far more weight than a standard nostalgia-driven re-release. With Avengers: Doomsday arriving just months later, Joe Russo has revealed that the new theatrical event will directly connect the 2019 blockbuster to Marvel’s next major crossover — and he has gone as far as calling it “required viewing.”
That instantly changes the conversation around the return of one of the MCU’s biggest films. Avengers: Endgame Encore arrives in theaters on September 25, 2026, while Avengers: Doomsday follows on December 18, and Marvel has already confirmed that the Encore event includes an exclusive preview of the upcoming Avengers movie.

Avengers: Endgame Encore Release Date and Why Marvel Is Bringing It Back Before Doomsday
The original Avengers: Endgame brought the Infinity Saga’s first major chapter to a dramatic conclusion when it arrived in 2019. Seven years later, Marvel is sending the film back to cinemas with additional material specifically designed to lead audiences toward Avengers: Doomsday.
During an interview with Fandango, Joe Russo explained why Marvel believes audiences should revisit Endgame before the next Avengers installment.
“Avengers: Endgame Encore is going to connect the story of the two movies. There’s a natural progression from Endgame into Doomsday, which is also inclusive of all the other stories that have been playing out. But I think it’s important to see Endgame again in theaters for two reasons: One, you’re going to have a lot of fun … and two, I think it’s required viewing for following the story in Doomsday.”
That is the clearest indication yet that Marvel does not view Endgame Encore as simply another opportunity for fans to experience the 2019 blockbuster on the big screen.
According to Joe Russo, the additional material will help establish the narrative progression between Endgame and Doomsday. That gives the re-release a very different purpose from a traditional anniversary screening or nostalgia event.
The choice of Endgame as the bridge also makes sense within the MCU’s larger story. The 2019 film dealt with the aftermath of Thanos’ destruction and brought the original Avengers era to a dramatic conclusion. Doomsday, meanwhile, is set to reunite heroes and characters from different parts of Marvel’s cinematic history.

Anthony Russo Teases New Endgame Encore Footage Fans “Couldn’t See Coming”
Joe Russo was not the only director teasing something unexpected.
Anthony Russo, who is co-directing Avengers: Doomsday alongside his brother, also discussed the new material during the Fandango conversation. Speaking about what fans who watched Endgame during its original theatrical run can expect from the Encore version, he said:
“If you saw Endgame when it was originally released, you couldn’t see this coming.”
That comment suggests the new footage is intended to deliver something genuinely unfamiliar, even for viewers who have revisited Endgame repeatedly since 2019.
Marvel’s own announcement describes Endgame Encore as featuring an exclusive preview of Avengers: Doomsday. That confirms the theatrical return is being used to build anticipation for the MCU’s next Avengers event rather than simply replaying one of Marvel’s biggest hits.

Why the Avengers: Doomsday Connection Makes This Re-Release More Important
The significance of Endgame Encore becomes even more interesting when looking at the scale of Avengers: Doomsday.
The upcoming film is being directed by Joe and Anthony Russo and is scheduled to arrive in theaters on December 18, 2026. Robert Downey Jr. is returning to the MCU in the role of Doctor Doom after his decade-long run as Tony Stark/Iron Man.
Chris Evans is also returning, alongside Chris Hemsworth, Anthony Mackie, Paul Rudd, Pedro Pascal, Vanessa Kirby, Simu Liu, Sebastian Stan and a large ensemble of Marvel characters.
The cast also includes major figures from Marvel’s X-Men and Fantastic Four history, including Patrick Stewart, Ian McKellen, Kelsey Grammer, Joseph Quinn and Ebon Moss-Bachrach. Marvel’s official listing confirms the film’s December 18 release and its extensive ensemble.
That makes the connection between Endgame and Doomsday especially intriguing. Endgame closed one defining era of the MCU, while Doomsday is bringing together characters and storylines that extend far beyond the original Avengers lineup.

Avengers: Endgame Encore Has Four Extra Minutes — But Marvel Is Keeping Its Biggest Secrets Quiet
The Encore version is listed at approximately three hours and five minutes, compared with the original film’s three-hour-one-minute runtime. That means audiences are not simply getting the exact same theatrical cut again.
However, Marvel has not fully revealed the precise contents of all the new material.
What is officially established is that the re-release contains an exclusive Avengers: Doomsday preview, while Joe Russo’s comments make clear that the additional material is intended to connect the stories of the two films.
That distinction matters. Fans can speculate about which characters, events or revelations could appear in the added footage, but those theories should not be treated as confirmed plot details until Marvel officially reveals them.

Joe Russo’s “Required Viewing” Comment Gives Endgame Encore a Bigger Purpose
Marvel could have easily turned the return of Avengers: Endgame into a straightforward nostalgia event. Instead, the Russo brothers’ comments suggest Endgame Encore has a much more specific role in the MCU’s next chapter.
Joe Russo is not merely encouraging fans to revisit the Infinity Saga finale because it remains an important part of Marvel history. He explicitly says the Encore edition will “connect the story of the two movies” and calls it “required viewing” for following Avengers: Doomsday.
That does not necessarily mean someone who skips the theatrical re-release will be completely unable to understand Doomsday. Russo’s wording does, however, make clear that Marvel considers the new material meaningful to the story arriving in December.
For fans who have already watched Endgame countless times, Anthony Russo’s promise that the new material was something audiences “couldn’t see coming” in 2019 may be the biggest reason to return to theaters.
Avengers: Endgame Encore arrives on September 25, 2026, while Avengers: Doomsday follows on December 18. For the first time, the gap between Marvel’s Infinity Saga finale and its next massive Avengers event is being filled with new footage that the filmmakers themselves say audiences will need to see.
