UPDATE: We have a trailer and release date for Supergirl!
After her cameo alongside Superman, Lois Lane, Lex Luthor, Mr. Terrific and Green Lantern, Supergirl is set to take center stage on June 25, 2026. And as the trailer shows, Jason Momoa’s Lobo will also be making an appearance in this Kara Zor-El story.
Looking to learn more about Supergirl? Feel like you’ve seen her portrayed in live action before? Here’s what you need to know about Supergirl before her movie hits theaters.
Supergirl Movie FAQs
Who is playing Supergirl?
Milly Alcock has taken on the role of Kara Zor-El, a.k.a. Supergirl.
Family Matters
Kara is the older cousin of Kal-El, who is, of course, more commonly known as Clark Kent and Superman.
Now, despite being born first, Kara does not look older than her cousin. That’s because when she escaped Krypton, she found herself in suspended animation.
Unlike Corenswet’s Superman, Alcock’s Supergirl had a full-blown childhood on Krypton before it was destroyed. But, she was also still a kid when Krypton fell. So while her cousin has had a rough go in his own right, Kara is carrying a different sort of baggage.
Where have I seen Supergirl in live action before?
Supergirl has been seen live action twice:
- In Smallville, she was played by Laura Vandervoort.
- In the Supergirl show, she was played by Melissa Benoist. (This iteration also appeared in other Arrowverse shows.)
What’s To Come for Supergirl
Supergirl: Woman of Tomorrow has been cited as the comic book that will be looked to when developing the upcoming Supergirl movie. If you plan to read the eight-chapter series — which I highly recommend — it might be best to avoid these last few notes.
Breadcrumbs from Superman
When we finally see Alcock’s Supergirl show up at the end of Superman, Corenswet’s Kal-El expresses to his robot assistants that his cousin likes to go around to planets with red suns to party. That’s because a red sun makes Kryptonian weaker, unlike yellow suns.
As mentioned before, Supergirl has been through a lot. While Superman had the Kents to help him through things, Kara was on her own. So, it should come as no surprise that she handles things quite differently than her boy scout cousin.
More about character than plot
Tom King and Bilquis Evely’s comic book is more character-driven than plot-driven. It’s about exploring the pain of Kara’s past and her running away from those who know her first as “Superman’s cousin.” There’s an Old Man Logan essence to the story, despite Supergirl not being old.
Seems reasonable to expect the tone and pacing will feel similar to the comic, especially following her cameo in Superman. The plot is likely where Gunn will deviate in some capacity. (In the comic, Kara makes a bunch of different stops while dealing with an individual looking to hire her. Still usable, but presents more wiggle room.)
Although she’s very well established during the events of Supergirl: Woman of Tomorrow, this story fits in very nicely as an introductory piece for the character. In fact, don’t be surprised if it comes to be viewed as one of the better origin-type superhero movies.
