What is the story about?
Marvel Studios seems to have made some small changes to Avengers: Endgame ahead of its re-release to cinemas, with fans spotting differences in the film's
color grading and even a minor tweak to one of Robert Downey Jr's iconic character, Iron Man aka Tony Stark's, most memorable lines. The changes were unveiled in the first trailer for Avengers: Endgame Encore, which will be returning to cinemas on September 25, 2026. The Encore will also be a big event for Marvel fans before the next Avengers film, giving audiences a special sneak peek at Avengers: Doomsday.
Avengers: Endgame encore trailer looks different
The biggest change fans have noticed is the way the overall film looks. The Encore trailer is a bit different from the version currently on Disney+, with a more vibrant color grade applied to scenes. One of the best examples is the sequence of Thanos leading his army into the final battle. The new footage seems to have better contrast and saturation, with Thanos himself appearing more purple and less washed out than in the original version.
The contrast is especially interesting because Endgame was criticised for its muted visual palette upon release in 2019. Some felt the film was too reliant on brown, gray and desaturated tones, particularly during its massive final battle. The new footage could thus remedy one of the film's long-standing complaints.
But many fans are concerned and wary about taking the trailer comparisons as conclusive evidence of a new theatrical master. Occasionally trailers are color graded differently. And compression and video formats can make footage look different.
Tony Stark's dialogue has been changed
Marvel may have made another subtle change to one of the film's most memorable lines. In the original Avengers: Endgame, Tony Stark says, "When you mess with time, it tends to mess back." In the Encore footage, the line changes to: "When you mess with time, time tends to mess back."
The change is small, but Marvel fans have already started connecting it to the events expected to take place in Avengers: Doomsday. With the MCU still heavily invested in time travel, alternate realities, and incursions, the rewording could add something more to a line that could have new meaning in the Multiverse Saga.
That said, there is no confirmation yet that the dialogue change has been made to the full theatrical version.
Endgame Encore isn't an extended cut
But the changes don't mean a radically different version of the 2019 blockbuster. Marvel is promoting Endgame Encore as a theatrical re-release, not an extended or director's cut. The film itself should remain largely unchanged, with the only major new content being exclusive Avengers: Doomsday material.
There's been speculation online about possible changes to characters and scenes, but no confirmation that Marvel has substantially changed the cast or story. It seems the company is using the re-release as a means to bring one of the biggest theatrical events in the MCU back to cinemas, while also creating a direct link to the next Avengers chapter.
Would the changes impact Avengers: Doomsday?
The timing of the re-release is no accident. Avengers: Doomsday will continue the multiverse saga of the MCU, with Robert Downey Jr returning to the franchise in a new role as Doctor Doom. For Marvel, the decision to bring back Endgame with an exclusive look at the upcoming film is a way to connect the end of the Infinity Saga to the next phase of the MCU.
The visual upgrade would also generate more consistency between both films. If Doomsday has a brighter, more stylised visual identity, the updated Endgame footage could help the two eras feel less visually disconnected. But it is still speculation as to whether that is the real reason for the changes.
Endgame Encore could be another box-office event
There's already a lot of interest in the re-release. Avengers: Endgame Encore is said to be having a very strong first day of pre-sales for a modern re-release, surpassing the early performance of the Titanic 3D re-release.
The film is also coming back at a potentially important time for Marvel ahead of Doomsday, given that Endgame is still one of the biggest theatrical experiences in modern cinema.
