Marvel has released a brief teaser for the upcoming film Avengers: Doomsday, featuring new dialogue from Pedro Pascal as Reed Richards and Vanessa Kirby as Sue Storm. The clip appears to depict the Fantastic Four in a race against time, with Storm asking, "How long do we have?" to which Richards replies, "Not long."

The teaser intersperses this new audio with a scene from last year's The Fantastic Four: First Steps, where Richards is shown touring the Baxter Building and referencing his family's Sunday dinner tradition. The abrupt cut to black and subsequent urgent dialogue suggest that this dinner, and perhaps much more, will be significantly disrupted.

This release comes shortly before a major Marvel showcase expected at San Diego Comic-Con, where further details about Avengers: Doomsday are anticipated. The current teaser offers a cryptic hint, potentially tying into the post-credit scene of The Fantastic Four: First Steps, which showed a toddler Franklin Richards in Doctor Doom's possession. The Fantastic Four's subsequent arrival in the main MCU reality, as depicted in the post-credit scene of Thunderbolts*/The New Avengers, may also be connected.

Speculation among fans also points to the possibility of multiverse collapse and Incursions as the cause of the Fantastic Four's predicament, suggesting they might be witnessing their reality colliding with another. The nature of these events remains unconfirmed, but the brief teaser has fueled hopes for more similar clips leading up to the film's debut.

While teaser trailers have been released previously, the full trailer for Avengers: Doomsday has so far only been shown to CinemaCon attendees. More information is expected from San Diego Comic-Con this weekend. The film is slated for a December 18 release, with tickets anticipated to go on sale this week. Reports indicate Avengers: Doomsday will have a runtime of 2 hours and 45 minutes. Fans are advised to be wary of leaked footage circulating online, with the film's release date approaching.
