The directors of Avengers: Doomsday, Joe and Anthony Russo, have shared details about the film's length, stating it will be approximately 2 hours and 30 minutes, making it one of the longest Marvel films to date. The film is described as an "engaging and dynamic story" with a "very surprising ending," according to the directors. Anthony Russo noted that the film's exact runtime may still be uncertain due to recent reshoots that added additional scenes. Only three previous Marvel films have exceeded 2 hours and 30 minutes (150 minutes): Eternals (157 minutes), Black Panther: Wakanda Forever (161 minutes), and Avengers: Endgame (3 hours and 1 minute or 181 minutes). Russo emphasized that the film is structured around a central organizing principle to ensure it remains engaging for audiences. The directors suggested the ending would be unexpected and that the story of Doctor Doom would not be concluded, likely setting up the upcoming Avengers: Secret Wars. Comparisons have been drawn to Avengers: Infinity War, which ended with the Avengers' defeat by Thanos, but the directors have not confirmed if a similar outcome will occur in Doomsday. The Russo brothers have also promoted Avengers: Endgame Encore, a special release that includes four previously unreleased scenes not included in Doomsday. One of these scenes shows Doctor Doom "capturing" Hulk, suggesting he may not participate in Doomsday and will return in Secret Wars. Avengers: Doomsday is scheduled for a theatrical release on December 16. The film is expected to be a major event in the Marvel Cinematic Universe, with its length and narrative structure indicating a focus on complex storytelling and character development. Fans are eagerly anticipating the film's debut and its potential impact on future Marvel projects.
