Marvel Studios officially launched its theatrical re-release, Avengers: Endgame Encore, on September 25, 2026. The theatrical event is designed as both a promotional and narrative bridge to Avengers: Doomsday, which is scheduled to arrive in theaters on December 18, 2026.
Directors Anthony and Joe Russo, who returned to direct Avengers: Doomsday, chose to preserve the original film rather than alter its narrative structure. The directing duo noted that the original three-hour cut was left intact, commenting, “We weren’t going to mess with what that movie is.” Instead, Marvel added four minutes of newly shot footage across an extended ending scene and three post-credits sequences, which were produced concurrently with Avengers: Doomsday.
Roughly 24 hours prior to the official theatrical debut, unauthorized video recordings of all four additional scenes from international and early preview screenings leaked across social platforms, including X/Twitter. Disney and Marvel promptly issued copyright takedowns to scrub the footage online. Before the leaks disappeared, publications including IGN and Cosmic Book News reviewed the recordings and verified their authenticity against official studio production materials and subsequent promotional clips.
The new sequences carry significant multiversal implications. The additional footage directly addresses Steve Rogers’ time-travel retirement, explaining his branched timeline’s continuity paradoxes and setting up the character’s re-emergence in Avengers: Doomsday. In another sequence, set following the events of Spider-Man: Brand New Day, Bruce Banner (Mark Ruffalo) is seen recording a video log inside an underground bunker while attempting to synthesize a gamma-suppressing serum. This moment confirms Ruffalo’s previously unannounced inclusion in Avengers: Doomsday and reveals that Victor von Doom is actively capturing or recruiting key surviving Avengers.
Cosmic stakes escalate further as monitors depict Earth-10005, the Fox X-Men reality, colliding with an alternate Earth while alarms warn that over 3,000 universes are collapsing. The moment formally initiates the incursion-driven “Time Runs Out” storyline, setting up the collision between the core MCU and the Fox Marvel universe featured in promotional material for Avengers: Doomsday. Finally, a closing tag visually recontextualizes the anvil-hammering audio heard in 2008’s Iron Man and the original 2019 Avengers: Endgame release, showing Doctor Doom hammering his metal faceplate into shape.
Audience response has leaned positive regarding the narrative weight of the additions, especially the unexpected confirmation of Mark Ruffalo’s Hulk, the integration of the Loki / TVA ensemble, and the immediate stakes of multiversal collapse. However, the release strategy has sparked notable pushback. Entertainment commentators from outlets including Forbes and Gizmodo, alongside fan communities, raised objections to the release mechanics. Critics noted that asking audiences to sit through a 181-minute re-release for four minutes of teaser material felt more like a box-office boost than a substantive artistic re-edit, while also expressing frustration with tiered access, as premium large-format screenings in IMAX and Marvel’s “Infinity Vision” carried an exclusive additional sneak peek not shown on standard screens.
