Avengers: Doomsday directors Joe and Anthony Russo have commemorated a special milestone in the countdown to the release of their upcoming MCU tentpole by posting an official teaser, exactly one year before the film is due out in theaters. However, fans hoping to get their first proper look at Robert Downey Jr. as the villainous Doctor Doom will have to wait a little longer, as the short video doesn’t reveal much of anything – unlike the purported trailer leak that has been doing the rounds and causing an uproar this week.
The Russo brothers, who are known for employing intense secrecy measures to protect the productions of their Marvel blockbusters, decided to combat the recent wave of social media leaks that have sent MCU fans spiraling by sharing an official teaser for Avengers: Doomsday, which is scheduled to be released in theaters on Dec. 18, 2026 (just one year from today). The video, posted on their Instagram account, features a clapperboard for the film, followed by a clock showing the months, days, hours, minutes, and seconds counting down to the release of the massive crossover event, starting from the 12-month marker.
Before it ticks over to 55 seconds, the clock ominously glitches to reveal the word “Doomsday” across the digital interface and then returns to the countdown. It doesn’t give much away, but it does appear to be the same animation as the one that appeared at the end of the leaked trailer, effectively confirming its legitimacy. It also signals that the frustratingly brilliant marketing campaign for Avengers: Doomsday will now ramp up, with Disney and Marvel utilizing the next 12 months to promote the first part of the Multiverse Saga’s grand finale, with events expected to culminate with the release of Avengers: Secret Wars in December 2027.
‘Avengers: Doomsday’ Trailer: When Will It Come Out?
MCU fans who are feeling the Avengers: Doomsday drought when it comes to official promotional material for the film will soon be awash with new content to study, dissect, and analyze as four distinct trailers are set to arrive in the coming weeks as part of a theater-exclusive strategy packaged with screenings for Avatar: Fire and Ash. The rollout will reportedly show each trailer before the James Cameron-directed sequel for a week before switching to a different version, bringing audiences back to theaters time and time again.
There is currently no date for the online release of the Avengers: Doomsday trailers, but it is heavily speculated that the previews will debut to the wider public following the full rollout of the new Avatar film, which means fans might be waiting until the end of January for their first glimpse of the MCU team-up event (unless they plan on visiting the theater multiple times) — though there will undoubtedly be plenty of discussion between now and then, as any MCU fans heading out to watch Avatar: Fire and Ash will have insider knowledge of what is expected to be the biggest movie of 2026 despite several other major releases.
