Supergirl is still over six months away – at the time of this guide's latest update – from being released. But, while the DC Universe (DCU) movie won't be with us until June 2026, the potentially imminent arrival of its first trailer will reignite interest in the superhero's first big-screen adventure for over 40 years.
So, when might the first teaser for the film formerly known as Supergirl: Woman of Tomorrow be with us? You'll have to read on to find out. I promise you'll learn more about the movie if you do, too, including its actual launch date, confirmed cast, and story specifics.
Full spoilers follow for 2025's Superman flick. Potential spoilers follow for Supergirl and the graphic novel it's based on, too.

Supergirl will be released on June 26, 2026. That means Supergirl will make her DCU debut almost one year after Superman landed in theaters and – spoilers! – after she made a brief scene-stealing cameo in that film.
With principal photography wrapping in early May and post-production well underway, there's no reason why the DCU movie's first footage won't be with us soon, too. Speaking of which...
Supergirl trailer: is there one?
No. However, the DCU Chapter One movie's first teaser could receive its world premiere in the near future.
Indeed, the 2025 edition of Brazil Comic-Con (CCXP), which runs December 4 to 7, will mark the start of DC Studios' long-lead marketing push for its next film. And, with a new Supergirl tease dropping a big hint that a trailer could debut at CCXP, we might get our first official look at the flick very soon. Regardless, once a trailer 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 I expect to see:
- 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
- Ferdinand Kingsley as Elias Knoll
There are plenty of details about the above actors, the role they'll inhabit, and where you might have seen them before in my Supergirl cast and character guide, so read that to learn more.
As for potential character cameos, speaking to Deadline, DC Studios co-chief James Gunn didn't rule out an appearance from Chris Smith, aka Peacemaker. However, considering what happened to him in the Peacemaker season 2 finale, and the fact he doesn't show up in 'Supergirl: Woman of Tomorrow', I'd be amazed if he's part of proceedings.
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 because 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.
Originally, this film 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.
Despite its revised title, David Krumholtz told Nerdtropolis that Supergirl is "very true to the graphic novel", so we can expect the same story – give or take a few narrative tweaks for reasons I'll explain later – to be told in this movie.
We've already been given a glimpse of how authentic Supergirl will be to its literary counterpart, too. 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, so Krumholtz's comments can be taken at face value.
For those who haven't read the comics, here's an incredibly brief plot summary: Kara Zor-El crosses paths with a young warrior named Ruthye, who enlists Kara's help in finding Krem, a space pirate responsible for killing Ruthye's dad.
I'll refrain from saying anything else for now but, depending on what its first trailer divulges, I'll elaborate more on the aforementioned synopsis at a later date.
As I mentioned earlier, there are a couple of small story-based changes that may impact its plot.
For one, we don't witness events in 'Supergirl: Woman of Tomorrow' playing out from the titular hero's perspective. Instead, we see them 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.
The inclusion of Lobo is also another alteration from the source material. 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.

We haven't had to wait for this project for Alcock to make her DCU debut, either.
In Superman's final scene, 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, which you can see again in the movie's first poster that also puts a rebellious spin on Superman's 'Look Up' tagline.
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. Chatting to Rolling Stone, Gunn said Supergirl will be "its own thing", so it might be a standalone space opera with, Kara's appearance in Superman aside, little to no connective tissue to the rest of the DCU.
That said, in May, Warner Bros. CEO David Zaslav told investors that Supes and his cousin, plus Wonder Woman and Batman, are the DCU's "big asset builders" (per Yahoo). It's possible, then, that Kara Zor-El's next cinematic adventure will be more important to this franchise than we realize.
Right now, what is clear is that Supergirl, aka the fourth DCU project to be released after season 1 of Creature Commandos, Superman, and Peacemaker season 2, won't be the final DCU project we see in 2026.
Arriving sometime in mid-2026, Lanterns, the DCU's first Green Lantern project, air on HBO Max in the US and Australia, and other streamers in other nations. For more, find out everything we know so far about Lanterns.
Then, in September, Clayface, a small-budget horror flick from Mike Flanagan, will arrive in theaters, and reveal at the DCU's Gotham City and – whisper it quietly – potentially a glimpse at this nascent franchise's Batman. Again, you can learn more by reading my definitive Clayface guide.
Lastly, Creature Commandos season 2 and Man of Tomorrow, the latter being the sequel to 2025's Superman, are in development at DC Studios. The former has no confirmed release date, but you can learn more about it via my Creature Commandos season 2 hub. As for the latter, it'll be released worldwide in July 2027 – get the scoop on that flick by checking out what we know so far about Man of Tomorrow, too.
In short: the future of the DCU looks bright and, hopefully, Kara Zor-El will continue to be an integral part of it moving forward.
