Overview
- Marvel announced that Avengers: Endgame returns to cinemas on September 25, 2026 as Avengers: Endgame: Encore and tickets and a trailer were released in late August.
- Exhibitor listings and studio statements show the runtime has grown by about four minutes to 185 minutes, and Marvel says the additions include a new introduction, extra footage and a post-credits tag tying Endgame to Doomsday.
- Trailer comparisons by fans and outlets report a refreshed color grade and a subtle Tony Stark line change, though Marvel has not published a full list of edits so those observations remain unconfirmed by the studio.
- Disney is rolling out Infinity Vision, a new Premium Large Format certification with technical standards for screen size, brightness and immersive sound, and audiences on Infinity Vision or IMAX screens will see additional Doomsday preview footage not available at regular showings.
- Marvel positions Encore as a marketing bridge ahead of Avengers: Doomsday on December 18, 2026, a strategy that mixes a technical refresh with targeted, tiered theatrical access and has prompted debate among fans about paywalled previews and unequal access to new material.
