Supergirl's next big-screen adventure still feels like a long way off. The DC Universe (DCU) movie is set to take flight in theaters on June 26, 2026, so it's still many months away from being released.
While you wait for the film's arrival, there's lots for you to read about it. Below, I've rounded up the biggest and most important information on the movie that was initially called Supergirl: Woman of Tomorrow. Indeed, you'll learn more about its confirmed cast, story details, and more from this moment on.
Major spoilers follow for James Gunn's Superman movie. Potential spoilers also follow for Supergirl and the graphic novel it's based on.

Supergirl will debut worldwide on June 26, 2026. That means Supergirl will make her DCU debut almost one year after Gunn's Superman movie was released and – spoilers! – after she made a brief scene-stealing cameo in Superman's latest silver screen outing.
Although he's not directing it, Gunn confirmed (via Threads) that principal photography wrapped in early May. With its post-production phase now well underway, there's no reason why the DCU movie won't arrive on time.
Supergirl trailer: is there one?
No. However, according to The Wrap, Gunn and company will showcase Supergirl at a major convention this fall/autumn (that's spring for southern hemisphere readers).
Could a teaser for the DCU Chapter One project be released at New York Comic-Con (NYCC), which runs October 9 to 12? There's no mention of a Supergirl panel taking place on the NYCC 2025 schedule, so it's highly unlikely.
The next big convention that a trailer might be shown, then, at is Brazil Comic-Con (CCXP) in December. Once one is released, I'll update this section.
Supergirl cast: confirmed and rumored
Potential spoilers follow for Supergirl.
Based on who's confirmed and rumored to appear, here's who's expected to appear in the DCU movie:
- Milly Alcock as Kara Zor-El/Supergirl
- Eve Ridley as Ruthye Marye Knoll
- Matthias Schoenaerts as Krem
- Jason Momoa as Lobo
- David Krumholtz as Zor-El
- Emily Beecham as Alura In-Ze
There are plenty of details about the above individuals, the role they'll inhabit, and where you might have seen them before in my dedicated Supergirl cast and character guide. So, head over there to learn more.
Supergirl story speculation
Possible spoilers follow for Supergirl.
Supergirl doesn't have a story synopsis yet. However, it's already possible to draw some conclusions about its plot due to the fact that it'll draw heavily from 'Supergirl: Woman of Tomorrow'. That's the eight-issue graphic novel series written by Tom King and drawn by Bilquis Evely, which ran from June 2021 to February 2022.
For starters, this film originally retained the 'Woman of Tomorrow' subtitle that its comic book namesake has. However, in mid-June, Gunn confirmed its title had been shortened to Supergirl because he's sick and tired of seeing film names with subtitles.
Anyway, in 'Supergirl: Woman of Tomorrow', Kara Zor-El crosses paths with a young warrior named Ruthye, who enlists Kara's help in finding Krem, a space pirate who's responsible for killing her dad.
I won't spoil anything else about the plot because, by the sounds of it, Supergirl is a near-direct adaptation of 'Woman of Tomorrow'. It wouldn't be fair, then, to ruin what happens in it for anyone who hasn't read the source material.
It's worth point out, though, that 'Supergirl: Woman of Tomorrow' is unique in that it doesn't tell the story from the titular hero's perspective. Instead, we witness events through Ruthye's eyes, so I'm curious to see if this'll be the case in Supergirl, or if Kara will be our eyes and ears in this flick.
One change that has been made to the source material is the inclusion of Lobo. The near-immortal mercenary was originally part of the graphic novel, but was cut from the story late on. As Gunn revealed in June, Lobo is not only part of this movie's story again, but also vital to how it plays out.
That revision and the potential other one I discussed earlier aside, it seems like this flick will be incredibly faithful to its graphic novel counterpart. In January, Gunn revealed its first behind-the-scenes image, which showed Alcock's Kara in a place that'll be very familiar to DC fans. Sure, it's just a single picture, but I'll be surprised if this image isn't hinting at a near-identical retelling of the story told in 'Supergirl: Woman of Tomorrow'.

We haven't had to wait for this project for Alcock to make her DCU debut, either.
In Superman's final pre-end credits sequence, we see Kara crash land at the Fortress of Solitude, be amusingly (and drunkenly!) rude to Clark, get reunited with Krypto, and fly off for pastures new. That 30-second cameo was all I needed to have full confidence in the DCU's Supergirl movie, but Gunn has sparked further excitement over Alcock's performance by calling it "absolutely stunning".
Kara's scene-stealing moment also confirmed we'll see her comic-accurate costume in this film. You can catch another glimpse of it in the movie's first poster, which also puts a rebellious spin on Superman's 'Look Up' tagline, in the above X/Twitter post.
And what of the film's age rating? 'Supergirl: Woman of Tomorrow' is a pretty dark and gritty story, so its live-action interpretation could push the boundaries of what's considered to be a family-friendly or parental guidance (PG) film.
Speaking to a roundtable of journalists, which TechRadar attended, in August, Gunn dropped a big hint that Supergirl will carry a PG-13 rating in the US. It won't be child-friendly, then, but it won't be a movie that's off-limits to anyone under 15 years old, either.
How will Supergirl impact the DCU?
The short answer is: I don't know. Supergirl will be the fourth DCU project released after season 1 of Creature Commandos, Superman, and Lanterns. The last of those is the next HBO TV Original that'll also air on HBO Max (US and Australia) and is expected to launch in early 2026. You can read more about it in my dedicated Lanterns guide.
Post-Supergirl, the only other DCU production in active development is Clayface. A small-budget horror flick from Mike Flanagan, it's currently penciled in to arrive next September and, based on what's been publicly revealed, it's highly unlikely to have ties to this film. Again, you can learn more in my dedicated Clayface guide.
Until the Daughter of Krypton's next standalone adventure is out, then, we can't say what the future holds for Kara Zor-El, or how her first DCU solo movie will impact the DCU.
What we do know is Warner Bros. Discovery (WBD) is positioning her as the fourth superhero that the nascent cinematic franchise is being built around. In May, WBD CEO David Zaslav told investors that Supes and his cousin, plus Wonder Woman and Batman, are the DCU's "big asset builders" (per Yahoo). In short: this isn't the last we'll see of Kara in the DCU.
