The first official teaser trailer for the DC Universe’s Supergirl movie, starring Milly Alcock, is set for release the week of December 8, 2025. The film, a darker adaptation of Supergirl: Woman of Tomorrow, arrives in theaters on June 26, 2026, and will feature Jason Momoa as the fan-favorite anti-hero Lobo.

The DCU’s Girl of Steel Takes Flight

The wait for the first solo Supergirl film since 1984 is almost over. Milly Alcock’s Kara Zor-El, who made her explosive debut in 2025’s Superman, is heading into her own cosmic adventure in James Gunn’s DCU Chapter 1: “Gods and Monsters.” With principal photography complete, fans are about to get their first full look at the film.

DC Studios head James Gunn has confirmed that the highly anticipated first teaser trailer will drop during the week of December 8, 2025, offering the first glimpse of Alcock’s standalone turn as the Woman of Tomorrow.

A Grittier Cosmic Odyssey: What We Know About the Film

Directed by Craig Gillespie (I, Tonya, Cruella) from a screenplay by Ana Nogueira, Supergirl draws direct inspiration from the acclaimed Tom King and Bilquis Evely comic series, Supergirl: Woman of Tomorrow. This promises a more rugged, interstellar journey for Kara, distinct from her cousin’s story.

Key Production Details:

• Director: Craig Gillespie
• Writer: Ana Nogueira (also writing Wonder Woman and Teen Titans for DC Studios)
• Source Material: Supergirl: Woman of Tomorrow by Tom King & Bilquis Evely
• Creative Architect: Tom King contributed to the film’s adaptation.
• Status: Principal photography wrapped in May 2025.

Star-Studded Cast & Major DCU Debuts

The film will feature several major players in the new DC Universe:

• Milly Alcock reprises her role as Kara Zor-El / Supergirl, with her loyal dog Krypto in tow.
• In a major franchise crossover, Jason Momoa transitions from the DCEU’s Aquaman to the DCU’s iconic Lobo. This marks the first major DCEU actor to be recast in a new role within Gunn’s universe.

Jason Momoa on Embracing the Main Man: Lobo

In an interview, Momoa shared his excitement and nerves about playing the character he’s always loved:

Jason Momoa: “Well, this is the role I’ve always wanted to play. That’s the comic I loved, so I’m really nervous about it. It’s kind of a no-brainer to play this character… we look pretty dead on, exactly like the character, and he’s pretty rough and gruff… I’ll say the bike’s really cool.”

When asked if audiences will see more of Lobo in the future, Momoa was hopeful but clear about the film’s focus: “I hope so. I hope so. It’s her movie, so it’s great. I just come in for a little bit.”
