The first official trailer for Avengers: Doomsday premiered at CinemaCon 2026, unveiling Robert Downey Jr. In the role of Doctor Doom and confirming the return of several Marvel Cinematic Universe stalwarts. The film, set for release on December 18, 2026, serves as the sequel to Avengers: Endgame and is positioned as the 39th installment in the MCU. Directed by Anthony and Joe Russo, with a screenplay by Michael Waldron and Stephen McFeely, the movie brings together the Avengers, Wakandans, Fantastic Four, Novel Avengers, and X-Men to confront Doom’s multiversal threat.
According to verified reports from Variety, the trailer opens with Downey Jr.’s Doctor Doom, clad in his signature green hood and metal armor, preparing to invade the multiverse. A pivotal scene shows Doom catching Thor’s enchanted hammer Mjolnir with his bare hands during a confrontation with Chris Hemsworth’s Thor. The footage also features Professor Charles Xavier (Patrick Stewart) gazing from his X-Mansion window as a bright flash signals impending danger, followed by rapid-cut crossovers including Gambit (Channing Tatum) and Shang-Chi (Simu Liu) in battle, and a surreal fight between Mystique (Rebecca Romijn), who transforms into Yelena Belova, and Florence Pugh’s character.
The most emotionally resonant moment in the trailer arrives when Chris Evans reprises his role as Steve Rogers/Captain America, reuniting with Thor in a scene that underscores the narrative weight of his return. As noted in the Variety coverage, Evans’ appearance comes after his character’s decision in Avengers: Endgame to return the Infinity Stones and live out his life with Peggy Carter in the past, thereby passing the shield to Sam Wilson. His reemergence in the present timeline is portrayed as a surprise to Thor, who had believed Rogers had aged peacefully in another era.
The film’s ensemble cast includes Vanessa Kirby, Anthony Mackie, Sebastian Stan, Letitia Wright, Paul Rudd, Wyatt Russell, Tenoch Huerta Mejía, Ebon Moss-Bachrach, Simu Liu, Florence Pugh, Kelsey Grammer, Lewis Pullman, Danny Ramirez, Joseph Quinn, David Harbour, Winston Duke, Hannah John-Kamen, Tom Hiddleston, Patrick Stewart, Ian McKellen, Alan Cumming, Rebecca Romijn, James Marsden, Channing Tatum, Pedro Pascal, and Robert Downey Jr. And Chris Evans. The production is a collaboration between Marvel Studios and AGBO, with distribution handled by Walt Disney Studios Motion Pictures. Newton Thomas Sigel serves as cinematographer, Jeffrey Ford as editor, and Alan Silvestri composes the score.
Avengers: Doomsday is being marketed as a direct continuation of the Multiverse Saga, following the previously announced films The Kang Dynasty and Secret Wars, which were revealed in July 2022 as the conclusion of Phase Six. Destin Daniel Cretton was attached to direct The Kang Dynasty, with Jonathan Majors set to reprise his role as Kang the Conqueror, while Jeff Loveness joined as writer for that project later in September 2022.
The trailer’s debut at CinemaCon marks a significant moment for the theatrical industry, which has faced challenges since the last major Avengers ensemble film in 2019. Exhibitors from across the United States welcomed the footage as a sign of renewed audience interest in large-scale franchise events. Marvel’s presentation at the convention included only four prior teasers focusing on individual characters—Steve Rogers, Thor, the X-Men, and the Fantastic Four—before unveiling the full-length trailer.
As the MCU prepares for this next chapter, fans and analysts alike are watching closely to notice how the film integrates the vast array of characters introduced over the past decade while advancing the overarching narrative of multiversal conflict. The film’s success may hinge on balancing spectacle with emotional resonance, particularly in honoring long-standing character arcs while introducing new dynamics.
