Marvel’s Avengers: Doomsday may be on deck for 2026, but the spotlight has shifted–and it’s moved toward Pandora. Disney is preparing for its longest theatrical release in company history with Avatar: Fire and Ash, hitting theaters on December 19, 2025. According to AMC listings, the film runs 3 hours and 15 minutes, officially topping Avatar: The Way of Water’s 3 hours and 12 minutes from 2022.
The rise of extended runtimes across major franchises has roots in 2019’s Avengers: Endgame. The 3-hour and 2-minute length surprised audiences at the time, especially considering no Marvel film had ever been that long. But the payoff wasn’t just box office success–it reshaped audience expectations.
Endgame showed that viewers would accept lengthy narratives if the stakes and scope were clear. Its status as the longest Disney-distributed movie at over 170 minutes opened the door for what followed: Avatar’s return to the top of the runtime chart.
Avatar: Fire and Ash goes even further. The film features new volcanic environments and introduces the Ash People, a Na’vi faction that breaks from previous depictions of harmonious tribes. Oona Chaplin portrays Varang, leader of an aggressively independent group that actively rejects Eywa, the spiritual force central to Na’vi belief. This approach brings fresh conflict within Pandora, moving away from a single-sided battle with humans toward deeper ideological division.
James Cameron revealed to Entertainment Weekly that the film’s title carries thematic weight, noting that fire represents “hatred, anger, violence” and ash represents “the aftermath.” He has reportedly completed post-production and, as The Direct shared, the finished film is “more intense, more emotional, and bigger in scale” than anything seen in the franchise so far.
Theatrical run times of three hours or more have become increasingly common–especially in franchise storytelling. Avengers: Doomsday arrives December 18, 2026, but Kevin Feige and the Russo Brothers have confirmed it will serve as a new starting point rather than a conclusion. That could leave Avengers: Secret Wars, scheduled for December 17, 2027, to take the longer route.
