Supergirl Teaser Released; Full Trailer Expected Soon

The first teaser for the upcoming film Supergirl has been officially released, generating excitement among fans. The brief 10-second clip, which debuted on December 7, 2025, showcases Milly Alcock in the titular role, providing a glimpse of her character’s demeanor as she dons oversized sunglasses while a spaceship lands nearby.

As anticipation builds for the film, set to hit theaters on June 26, 2026, James Gunn, co-head of DC Studios, has confirmed that the full trailer will be released soon. Initially, speculation suggested that the trailer might premiere at Brazil Comic-Con (CCXP) 2025, which took place from December 4 to 7; however, this did not occur. Instead, the teaser was showcased at a private event in New York City on the same day it was released to the public.

According to entertainment reporter Erik Davis, select members of the press were able to view the full trailer during this exclusive event. This private unveiling sets the stage for a public release that could occur imminently. The announcement accompanying the teaser hinted at a trailer launch “this week,” a timeline echoed by Gunn on his personal Threads account.

While an exact date for the trailer’s release remains unconfirmed, there are rumors suggesting it could debut on December 11, 2025. This information comes from industry insider DanielRPK, known for accurately predicting trailer release dates. However, the potential release of the trailer for the highly-anticipated Avengers: Doomsday on the same day could complicate matters for DC Studios. The competition for viewer attention on that date may lead to a strategic delay in Supergirl‘s trailer release.

As fans await further updates, the excitement surrounding Supergirl continues to mount. The film is expected to be a significant addition to the DC Universe, especially following Alcock’s standout cameo in this year’s Superman film. For those keen on keeping up with the latest developments, further details about the film’s cast and characters are available in dedicated guides.

The buzz around Supergirl reflects a broader enthusiasm for superhero films, with audiences eager to witness the next chapter in the DC franchise. The release of the full trailer is a highly anticipated event, promising to reveal more about the storyline and characters that fans have been eagerly discussing.
