Avengers Endgame box office history has a new leader again. Marvel's Encore re-release has pushed the 2019 superhero epic past James Cameron's Avatar, making Endgame the highest-grossing film of all time once more with a lifetime worldwide total of about $2.9255 billion against Avatar's roughly $2.9237 billion, according to figures reported by SlashFilm, citing Variety. The gap between the two films is less than two million dollars, the thinnest margin ever seen at the top of the all-time chart, and it could shift again as both movies remain in circulation.

The flip was engineered by Avengers Endgame: Encore, the extended cut Marvel returned to theaters on September 25 with new footage tied to Avengers: Doomsday. The re-release has collected roughly $126 million worldwide on its own, per tallies reported by Deadline, and that haul alone did the work of moving Endgame past Avatar. Encore opened at number one in North America and drew crowds who have had years of streaming access to the film, which suggests the new material gave fans a concrete reason to show up in person.

How Encore flipped the chart

Encore's opening weekend brought in about $86 million worldwide, including roughly $26 million from domestic theaters, ranking it among the biggest re-release openings on record. Marvel added about four minutes of new footage spread across four scenes, with a storyline thread in which characters from the Time Variance Authority witness the collapse of the multiverse, giving the re-release a hook a straight reissue would not have had. The new scenes function as a bridge into Doomsday's story, which Marvel has positioned as the next major event in its cinematic universe. Rentrak's head of market trends, Paul Dergarabedian, told SYFY Wire that re-releases let people who only saw these films on small screens experience them as intended, in theaters with fellow fans.

The rollout has been strongest outside the United States. Trade reports note the re-release became the biggest of its kind in Latin America, India, and Indonesia, and it held as the top non-local title in China during its second frame. That international muscle explains how a seven-year-old film could generate nine-figure revenue in a fortnight and reset a record that had looked settled. The Encore debut ranks just behind the 2012 3D re-release of Titanic among global re-release openings. Theater owners welcomed the numbers, since a proven title filling screens in the fall corridor is exactly the kind of booking that keeps auditoriums busy between tentpole releases.

A record that keeps changing hands

Avatar originally set the record during its 2009 theatrical run, finishing with about $2.74 billion and holding the crown for nearly a decade. Endgame first took it in the summer of 2019, closing its original run near $2.79 billion. Avatar grabbed it back in 2021 through a re-release in China, and now the crown has swung back to Marvel five years later. Both titles sit under the Disney umbrella after the company's acquisition of 20th Century Fox, so the studio comes out ahead whichever film sits on top. The back-and-forth has become a fixture of box office lore, with each swing arriving courtesy of a carefully timed re-release rather than a fresh blockbuster.

The timing is anything but accidental. Avengers: Doomsday opens on December 18, with Joe and Anthony Russo back in the director's chairs and Robert Downey Jr., who played Iron Man for a decade, cast as Doctor Doom. The Russo brothers have called Endgame required viewing before Doomsday, and Encore effectively serves as the opening act of the new film's marketing campaign. Doomsday recently became the earliest film to reach $50 million in domestic advance ticket sales, according to WDWNT, which suggests the strategy is working. Marvel has turned its own back catalog into a promotional engine, and the box office crown is the headline it bought with the move.

Whether Avatar answers with another re-release is the question now hanging over the chart. Whatever happens next, the Avengers Endgame box office crown remains one of the most contested titles in modern cinema. The margin is so thin that even a modest limited run could flip the ranking once more, and Cameron's film has already shown it can fight back from behind. The next test comes December 18, when Doomsday opens and Marvel's full marketing push moves into its final phase.
