Robert Downey Jr. Arrives as Doctor Doom in ‘Avengers: Doomsday’ Footage
Marvel Studios unveiled the first official footage of Avengers: Doomsday at CinemaCon 2025, confirming Robert Downey Jr.’s return to the Marvel Cinematic Universe as Doctor Victor Von Doom. The presentation, held during the annual convention of theater owners in Las Vegas, featured a teaser trailer that showcased the actor in full regalia as the iconic Marvel villain, marking a significant shift from his previous role as Tony Stark/Iron Man.
According to reports from The Hollywood Reporter and Variety, the footage revealed Downey Jr. Portraying Doom with a redesigned suit that blends elements of the character’s classic armor with a more futuristic, tech-driven aesthetic. The trailer depicted Doom confronting the Avengers, Wakandans, Fantastic Four, and X-Men, setting up a multiversal conflict that positions him as the central antagonist of the film.
The announcement confirms that Avengers: Doomsday will serve as a direct sequel to Avengers: Endgame (2019) and is positioned as the 39th film in the Marvel Cinematic Universe. Directed by Anthony and Joe Russo, who returned to the franchise after helming Avengers: Infinity War and Endgame, the film is written by Michael Waldron and Stephen McFeely. It is produced by Marvel Studios in collaboration with AGBO and distributed by Walt Disney Studios Motion Pictures.
Principal photography for Avengers: Doomsday began in early 2025, with filming taking place at Pinewood Studios in the United Kingdom and various locations across Atlanta, Georgia. The film’s release date is set for December 18, 2026, as confirmed by multiple industry outlets including IMDb and Marvel’s official communications.
The CinemaCon presentation also included brief glimpses of other returning and new cast members. Chris Hemsworth reprises his role as Thor, seen wielding Mjolnir in a confrontation with Doom. Chris Evans appears in a brief but pivotal moment, lifting the hammer in a sequence that suggests a potential alternate timeline or multiversal variant of Captain America. Additional footage showed the X-Men, including Wolverine and Storm, engaging in battle sequences, confirming their integration into the MCU narrative following Marvel’s acquisition of 20th Century Fox’s film assets.
The film brings together characters from multiple franchises within the Marvel universe, including the Avengers, Wakandans, Fantastic Four, New Avengers, and the X-Men, all uniting to face the threat posed by Doctor Doom. This crossover event marks one of the most ambitious team-ups in MCU history, building toward the culmination of the Multiverse Saga.
Marvel Studios has not released an official trailer to the public as of yet, but the CinemaCon footage has generated significant anticipation among fans and industry observers. The decision to cast Downey Jr. As Doom—rather than reprising Tony Stark—has been widely discussed as a bold narrative choice, allowing the actor to explore a darker, more complex character arc while maintaining his central role in the franchise’s next chapter.
Avengers: Doomsday is expected to have major implications for the future of the MCU, particularly in resolving ongoing multiversal storylines introduced in Loki, What If…?, and Doctor Strange in the Multiverse of Madness. With its release still over a year away, the film remains one of the most highly anticipated projects in contemporary cinema.
