Disney announced that the re‑release of Avengers: Endgame, titled Avengers: Endgame Encore, will feature two sneak peeks of the upcoming film Avengers: Doomsday during select theater showings, with one preview limited to IMAX and Infinity Vision‑certified screens; the added footage extends the film’s runtime by roughly four minutes.

The announcement follows a press release from Disney UK dated August 25, which stated that the re‑release will include a preview of Doomsday and that the additional material accounts for the extra minutes observed by fans when AMC listed showtimes.

Director Joe Russo said the re‑release is intended to create a bridge between Endgame and Doomsday, offering a way to transition to the next installment. The footage shown is described as part of the Doomsday story but its exact content and duration remain unspecified. Fan reactions on social media range from skepticism about paying for a three‑hour screening of a previously seen film to speculation that the added material may appear as a short online video. Some observers note that releasing downloadable content for a seven‑year‑old movie is unusual. The Doomsday film itself is scheduled for release on December 18, 2026, and early speculation about Robert Downey Jr.’s casting as Victor Von Doom has generated discussion, though no official details have been provided.

The re‑release will run until the Doomsday premiere in late 2026, and whether the added previews justify the extended viewing time remains undetermined.
