DC Studios has officially revealed when the first trailer for Supergirl will be with us – and, as the rumor mill suggested, it will be within the next 24 hours.
On Monday, December 8, it was announced that Supergirl‘s first teaser would be released before the end of the week. This meant it could arrive anytime between the aforementioned date and Friday 12 December. Now we know exactly when it will premiere: Thursday 11 December at 8:59 a.m. PT / 11:59 a.m. ET / 4:59 p.m. GMT.

The confirmation comes in the form of a trailer reveal placeholder, which went live on DC Comics’ YouTube channel today (December 10). And if that wasn’t enough to whet our appetite for the teaser’s reveal, the accompanying image also gives us a new look at Milly Alcock’s titular character.
Wearing Supergirl’s iconic suit and the brown trench coat she was seen wearing in her scene-stealing cameo in this year’s Superman film, Alcock looks every inch the rebellious hero. It’s the same outfit that Kara Zor-El sports in ‘Supergirl: Woman of Tomorrow’, aka the graphic novel that this DC Universe (DCU) film is also based on, which we also got a further glimpse of in Supergirls punk-rock style first poster.
But wait, there’s more! In the caption accompanying the trailer’s placeholder, DC and parent company Warner Bros. Pictures also dropped the first story synopsis for the DCU Chapter One movie.
“SupergirlDC Studios’ newest feature film for the big screen will be in theaters worldwide this summer from Warner Bros. Pictures, starring Milly Alcock as Supergirl/Kara Zor-El. Craig Gillespie directs the film from a script by Ana Nogueira.
“When an unexpected and ruthless adversary hits too close to home, Kara Zor-El, aka Supergirl, reluctantly teams up with an unlikely companion on an epic, interstellar journey of revenge and justice.”
Anyone who has read ‘Supergirl: Woman of Tomorrow’ will know what the aforementioned logline refers to. If you want to learn more about the movie’s plot before the teaser comes out, I’d recommend reading the plot section in my Supergirl guide. Don’t worry, it doesn’t contain any major spoilers, but it will give you some extra information about what to expect from one of 2026’s most exciting new movies.
