Supergirl 2026: Release Date, Trailer, Cast, Plot, and Everything You Should Know

Superman has rightfully revived DC, and now that it is soaring high in every aspect, the future of DC seems to be bright. In Superman, we got to see multiple heroes as well as villains, but one appearance truly stood out the most, and I guess you have already guessed who is being referred to here. I am talking about the cameo from Supergirl that foreshadows her upcoming solo movie, Supergirl. So, if you are curious about details about Supergirl, releasing in 2026, here is everything you should know about its release date, trailer, cast, plot, and more.

What Is the Release Date of Supergirl 2026?

Supergirl movie was initially slated to be released much later in the DC universe, but after James Gunn took over and became the CEO of DC Studios, he moved the movie up in the slate and made it the second movie to come out of the newly established DCU. So, Supergirl movie has been given the release date of June 26, 2026.

Is There a Trailer For Supergirl 2026?

Supergirl has already wrapped up filming and is in post-production. However, since final touches are being added to the movie, there is no trailer for Supergirl as of now, but we do have a poster shared on X by James Gunn. While there is a lack of details regarding when the trailer might drop, DC Studios could follow the same pattern as that of Superman (2025) and release the trailer for Supergirl sometime in December 2025. So, let’s wait and see what happens.

Who are the Cast Members of Supergirl 2026?

Not a lot of cast members are confirmed for Supergirl 2026 as of now, but we have a few names with confirmed appearances. First off, the star of the movie, Supergirl, is being played by Milly Alcock, and in all honesty, James Gunn couldn’t have chosen a better actor to play Supergirl. Looking at the way she appeared in Superman, it’s safe to say that Supergirl is going to turn out to be as much of a banger as Superman turned out to be.

Other than that, Jason Momoa is also confirmed to appear in Supergirl as Lobo. In an interview, he confirmed that initially, he went on to join Zack Snyder’s DCEU because he believed that he was being cast as Lobo. Along with Momoa, we will also get to see the appearance of Matthias Schoenaerts, as Krem Of The Yellow Hill, the apparent main antagonist of Supergirl. We will also witness the cinematic debut of Eve Ridley as Ruthye Marye Knoll. Moreover, since Supergirl had a cameo in Superman, there might be a chance that David Corenswet could possibly cameo in the upcoming movie as well, but we don’t have a confirmation so far.

• Milly Alcock– Kara Zor-El/Supergirl
• Jason Momoa– Lobo
• Matthias Schoenaerts– Krem Of The Yellow Hill
• Eve Ridley– Ruthye Marye Knoll
• David Corenswet– Clark Kent/Superman (Rumoured)

Who Is the Actress Playing Supergirl in the DCU?

Supergirl is played by Milly Alcock in the DCU, and if you don’t know who she is, there’s a good chance that you are missing out on some pretty cool movies and TV shows out there. She has appeared in shows like House of the Dragon, Upright, and A Place to Call Home. Other than that, she has appeared in movies like The Familiars, Les Norton, and Sirens.

What Could Be the Plot of the Supergirl Movie?

Now, while we don’t have a lot of information about the plot of Supergirl 2026, we are aware of the fact that the story of this movie will be adapted from a comic book of the same name. So, based on that, we can draw assumptions about what Supergirl is going to be about.

According to the comic, Supergirl leaves Earth to celebrate her 21st birthday on a different planet, where she meets Ruthye, who is seeking revenge for the death of her father. Supergirl decides to help Ruthye even though she was on a planet with a red sun. So, there is a good chance that we might get to see this story being adapted into the upcoming movie.
