The first official teaser for Avengers: Doomsday is on the way, and we now know exactly how long it is. According to a listing on the official Korea Media Rating Board website, the debut teaser has a runtime of 1 minute and 25 seconds. This brief but exciting first look is expected to play in theaters starting December 19, 2025, attached to screenings of James Cameron’s Avatar: Fire and Ash. While it’s short, this early peek is a major signal that Marvel Studios is kicking off its long promotional campaign for one of its biggest movies ever.
How Long Is the New Teaser and When Can You See It?
The reported length of 1 minute and 25 seconds (or 85 seconds) is a key piece of information for eager fans. A trailer appearing on a ratings board website often means its release is very close, sometimes just a day or two away. This suggests the official online release from Marvel could happen very soon.
The trailer is confirmed to debut in movie theaters. It will be attached to Avatar: Fire and Ash, which opens on December 19, 2025. It is not yet clear if Marvel will also release the teaser online on that same date or choose to share it a few days earlier. Marvel often releases trailers online at the same time they hit theaters to control the quality of the first look.
This early teaser arrives more than a full year before Avengers: Doomsday opens in theaters on December 18, 2026. This long lead time is a change from Marvel’s usual schedule and helps explain why the first look is a shorter teaser rather than a full trailer.
Why the First Trailer Is So Short
At just over a minute long, this will be the shortest first trailer for any Avengers movie in the history of the Marvel Cinematic Universe. For comparison:
- The first Avengers (2012) trailer was 2 minutes and 4 seconds.
- Avengers: Age of Ultron debuted with a 2-minute, 16-second trailer.
- Avengers: Infinity War and Avengers: Endgame had first trailers around 2 minutes and 25 seconds.
The shorter length is a direct result of the very early marketing timeline. With the movie still a year away, the goal of this teaser is not to explain the whole plot. Instead, it aims to set a tone, introduce the key threat, and generate massive online discussion with just a few powerful shots. This strategy is similar to how Lucasfilm marketed Star Wars: The Force Awakens, which also debuted with a 90-second teaser roughly a year before release.
“It’s a bit above a minute in lengthโฆ so purely a teaser and not a full trailer as some others were saying.” โ Entertainment insider @Cryptic4KQual on the trailer’s purpose.
Marvel is expected to release a longer, more detailed trailer at a major event in 2026, such as the Super Bowl or San Diego Comic-Con.
What Fans Hope to See in the 85-Second Teaser
Even with a short runtime, fans have big expectations for what this first look might show. The most important element will be the proper introduction of Robert Downey Jr. as Victor Von Doom. After playing Tony Stark for over a decade, Downey is returning as the legendary Marvel villain. The teaser needs to quickly establish him as a completely new and threatening character, not an evil version of Iron Man.
Another major draw is the promised return of legacy X-Men actors from the original 20th Century Fox films. The trailer is expected to feature actors like Patrick Stewart (Professor X) and Ian McKellen (Magneto) in costumes inspired by the classic comics and the X-Men ’97 animated series. A glimpse of this team could be one of the teaser’s biggest moments.
Given the large cast, the teaser will likely be a rapid-fire series of shots. Confirmed returning heroes include Chris Hemsworth as Thor, Anthony Mackie as Captain America, Letitia Wright as Black Panther, and Simu Liu as Shang-Chi. The movie will also feature the new Fantastic Four, with Pedro Pascal as Mister Fantastic and Vanessa Kirby as the Invisible Woman.
The Road to Doomsday: Cast, Release, and What Comes Next
Avengers: Doomsday is being directed by Joe and Anthony Russo, who previously directed Avengers: Infinity War and Endgame. The movie is a central part of Marvel’s Phase 6 and will be followed by Avengers: Secret Wars in 2027.
The film’s plot is a closely guarded secret, but it is confirmed that the multiverse will play a key role and that Doctor Doom is the main villain. The story will bring together heroes from across the MCU’s history and other Marvel film universes to face this threat.
The movie’s release date is set for December 18, 2026. With this teaser, the long wait for the next Avengers event officially begins. The short 85-second first look is just the starting point for a marketing campaign that will build over the next year.
