Avengers: Doomsday, everything you need to know: the big event that realigns the MCU
After Endgame, the first real test for the future of the Avengers.
Avengers: Doomsday represents a crucial turning point for the Marvel Cinematic Universe. Not only because it marks the first major ensemble film for the Avengers after Endgame, but because it stems from a profound creative and productive reorganization that has pushed Marvel Studios to redefine the antagonist, narrative structure, direction of the entire Phase Six, and cast composition. What has emerged so far outlines a project that is explicitly ambitious, designed to connect the Avengers, X-Men, and Fantastic Four within an unprecedented multiversal crisis.
The Plot of Avengers: Doomsday, what is it about?
A detailed official synopsis has not yet been released. Confirmed information indicates that the story is set fourteen months after the events of Thunderbolts* (2025) and sees multiple groups of heroes converge, from the Avengers to the New Avengers, passing through Wakandans, the Fantastic Four, and the “classic” X-Men, in the face of a common threat.
The film marks the full debut of Victor von Doom within the MCU, after his appearance in the mid-credits scene of The Fantastic Four - The Beginnings. The conflict revolves around the collapse of the Multiverse, a core theme of the ongoing saga, and the so-called “incursions” already introduced in previous chapters. Marvel has chosen to maintain almost total secrecy regarding the narrative developments, merely suggesting an ensemble structure in which different realities collide, forcing unprecedented alliances.
When is Avengers: Doomsday released?
In Italy, the film is scheduled for December 16, 2026, a date confirmed after a delay decided to allow more time for post-production. Avengers: Doomsday is officially part of Phase Six of the Marvel Cinematic Universe (here you can find the list of all chapters) and will serve as a direct prelude to Avengers: Secret Wars, already set for 2027.
The cast of Avengers: Doomsday
The announcement of the cast was one of the central elements of the film's communication strategy. Marvel has confirmed an ensemble that brings together historical MCU performers, new additions, and actors from the 20th Century Fox X-Men film saga.
Avengers
The Avengers group includes Chris Hemsworth as Thor, Anthony Mackie as Sam Wilson/Captain America, Paul Rudd as Scott Lang/Ant-Man, Tom Hiddleston as Loki, Simu Liu as Shang-Chi, and Danny Ramirez as Joaquin Torres/Falcon. These are joined by central figures of the New Avengers, including Sebastian Stan, Florence Pugh, Wyatt Russell, David Harbour, Hannah John-Kamen, and Lewis Pullman.
X-Men and Mutants
The film marks the formal entry of the “original” X-Men into the MCU. Returning are Patrick Stewart as Charles Xavier, Ian McKellen as Magneto, James Marsden as Cyclops, Rebecca Romijn as Mystique, Alan Cumming as Nightcrawler, Kelsey Grammer as Beast, and Channing Tatum as Gambit. Their presence confirms Marvel's desire to explicitly integrate the legacy of the Fox films into the multiversal narrative.
The Fantastic Four
The Fantastic Four are played by Pedro Pascal as Reed Richards, Vanessa Kirby as Sue Storm, Joseph Quinn as Johnny Storm, and Ebon Moss-Bachrach as Ben Grimm. Their historical connection to Doctor Doom constitutes one of the film's thematic cornerstones and represents a fundamental point of contact between the different narrative lines.
Wakandans
The Wakandan front sees the return of Letitia Wright as Shuri/Black Panther and Winston Duke as M’Baku, with the participation of Tenoch Huerta Mejía as Namor. Wakanda thus returns to occupy a central position in the geopolitical scenario of the conflict, now expanded to a global and multiversal dimension.
Doctor Doom
The role of Victor von Doom is entrusted to Robert Downey Jr. (an actor who had previously played Iron Man in the MCU), a choice announced during San Diego Comic-Con 2024. The Russo brothers described the character as one of the most complex figures in the Marvel universe, emphasizing how Downey Jr.'s interpretation aims to deliver a three-dimensional antagonist, far from a simple hero-villain dichotomy.
Steve Rogers and Peggy Carter
Also confirmed are Chris Evans as Steve Rogers and Hayley Atwell as Peggy Carter, along with other characters already seen in the MCU.
Other Characters
For some presences, Marvel has not yet provided definitive clarifications, maintaining deliberately selective communication. Hypotheses about possible appearances of Deadpool or Blade remain, for now, in the realm of speculation.
The Directors of Avengers: Doomsday
Anthony and Joe Russo, already responsible for Avengers: Infinity War and Avengers: Endgame, return to direct. The screenplay is written by Stephen McFeely, with contributions from Michael Waldron. The reunion of this creative team marks a conscious return to a narrative approach that has already proven capable of managing large casts and broad narrative arcs.
The Runtime of Avengers: Doomsday
The official runtime of the film has not yet been communicated. Marvel Studios has not provided any indications on the running time, which will only be announced closer to the theatrical release. However, rumors suggest a particularly long duration, in line with the ambition and scope of the project.
What does Avengers: Doomsday represent for the MCU?
Avengers: Doomsday is configured as a turning point rather than a simple intermediate chapter. It is the film called to reorganize the Marvel Cinematic Universe after years of fragmented expansion, bringing back to the center an idea of shared storytelling and collective event. The choice to intertwine the Avengers, X-Men, and Fantastic Four within an explicit multiversal crisis signals Marvel Studios' desire to finally give a unified direction to Phase Six, transforming the Multiverse from a narrative device into a true dramatic engine.
Doomsday not only promises a spectacular clash, but a moment of identity redefinition: of the MCU, its historical characters, and its relationship with the recent past. It is the film that must demonstrate whether the Marvel universe is still capable of reinventing itself without denying what has made it central to contemporary pop culture.
