Overview
- Disney and Marvel returned Avengers: Endgame to theaters as Avengers: Endgame: Encore, with the reissue playing from Sept. 25, 2026 in standard and certified longer premium cuts.
- Marvel added a few minutes of newly shot material to link Endgame directly to Avengers: Doomsday, with studio sources and attendees saying the scenes were filmed during Doomsday production.
- The Encore footage is described by multiple reports as introducing a major new antagonist portrayed by Robert Downey Jr. and as signaling wider multiverse threats and cross‑universe ties that connect to the X‑Men films.
- The release uses a new Infinity Vision premium certification alongside IMAX to show an extended cut in select auditoria, a strategy that places extra preview material behind higher‑grade tickets.
- Early IMAX previews produced scene-level reporting and unauthorized clips, prompting strong audience reaction at screenings and renewed debate about paywalled previews, spoilers, and how the reissue positions Doomsday for its Dec. 18 release.
