New Supergirl Movie Trailer Reveals Grittier, Rock & Roll Heroine for DCU

Warner Bros. has released the first teaser for the upcoming Supergirl movie. The film stars Millie Alcock of House of the Dragon fame. It arrives in theaters on June 26, 2025. This new take presents a starkly different Kryptonian hero.

Director Craig Gillespie and DC Studios co-head James Gunn are behind the project. They describe it as a “way more rock & roll film” compared to this year’s Superman. According to Rolling Stone, this Supergirl is tougher and more flawed.

Inspired by Acclaimed Comic Arc, Featuring a Hard-Partying Kara

The film draws direct inspiration from the 2022 comic Supergirl: Woman of Tomorrow. In that story, Kara Zor-El is deeply traumatized by the destruction of Krypton. She copes by hopping between alien bars across the galaxy.

The teaser trailer reflects this tone perfectly. It shows a hungover Supergirl with a vocal fry. Her loyal dog, Krypto, is also seen relieving himself on the moon. The footage is set to Blondie’s 1980 hit “Call Me,” reinforcing the gritty, rebellious vibe.

This portrayal is a conscious departure from the classic Superman archetype. James Gunn emphasized the character’s imperfections at a recent preview event. He noted that female heroes are often portrayed as perfectly polished, but this Supergirl breaks that mold.

A Different Kind of Hero Journey for the DC Universe

The film’s plot follows Supergirl teaming up with a young alien named Ruthye. Their mission is one of revenge against a murderous villain. This journey is more personal and brutal than a typical superhero save-the-day story.

This establishes a clear contrast within the new DC Universe. Superman represents hope and sees the good in everyone. As Supergirl states in the trailer, “I see the truth.” Her perspective is shaped by immense loss and a harder life in space.

The movie will also introduce other key characters. Alien bounty hunter Lobo, played by Jason Momoa, will appear. However, his role in the teaser is kept brief, focusing the spotlight firmly on Alcock’s Supergirl.

This new Supergirl movie promises to redefine a classic character for modern audiences. It offers a raw, rock-infused alternative to the superhero genre. The DCU’s future looks distinctly grittier with this Woman of Tomorrow.
