Formerly subtitled Woman of Tomorrow, the film will be a part of the new DC Universe, taking place in Chapter 1, titled “Gods and Monsters.” Led by James Gunn (Guardians of the Galaxy) and Peter Safran (Aquaman), DC Studios will be resetting their franchises in a new direction that is heavily based on the comics that made the brand a household name in the first.

With Superman set to mark the start of a new universe, it’s only fitting that Superman’s cousin will soon follow in his footsteps and continue his legacy. Here’s everything we know about the epic adventure Supergirl.

A new world of DC adaptations is just around the corner.

Who Is Supergirl?

Making her debut in Action Comics #252, Kara Zor-El, cousin of Kal-El, has been a staple of DC Comics since 1959. While her more famous relative was destined for greatness, Kara never wanted to be a hero. Her dream was to live a peaceful life on Argo City, but with Krypton’s impending doom, Kara’s parents put her in an emergency pod and sent her to Earth, the same planet as her infant cousin Kal-El.

Kara lost everything the day Krypton was destroyed, and then she woke up on earth with the power of a deity. Unfortunately for Kara, things take an even weirder turn as she quickly discovers that she wakes up decades after Krypton imploded, and her infant cousin is now over a decade older than her.

Kara struggles to adapt to her new reality fully. While Clark was able to have a normal life, she witnessed the destruction of her entire planet and must grapple with that along with her new powers. This is the key difference between Superman and Supergirl, leading to a slew of unique stories starring the Girl of Steel.

Kara eventually takes on the superhero mantle, leading to her becoming a member of the Justice League, a Red Lantern, and a part of the Legion of Superheroes. Supergirl’s strength doesn’t simply come from the Earth's yellow sun, but also the strength found within.

What Is 'Supergirl' About?

Supergirl will adapt the Tom King graphic novel "Supergirl: Woman of Tomorrow." In that story, Kara Zor-El travels across the galaxy to celebrate her 21st birthday with her loyal companion, Krypto the Superdog. She ends up meeting a young woman named Ruthye who is on a quest for revenge. She wants to hunt down the man who killed her father. Unfortunately, Kara is on a planet with a Red Sun, rendering her powerless, but that doesn’t stop her from doing the right thing.

Together, Ruthye and Kara travel across the galaxies to find the murderer and will take down anyone who stands in their way. Woman of Tomorrow is a character study of Kara Zor-El and shows her bravery, toughness, and also her insecurities making it one of the most powerful stories to come from DC Comics over the last few years. You can check out the story by purchasing the graphic novel linked below.

Who Will Play Supergirl?

Previously, Supergirl was played by Helen Slater in the 1984 movie Supergirl. Over three decades later, Melissa Benoist took up the mantle in the CBS series (later moved to The CW) Supergirl. Benoist would become the actor most associated with the character, having played her for nearly a decade and becoming a central figure in Arrowverse alongside Stephen Amell’s Green Arrow and Grant Gustin’s The Flash. Most recently, The Flash and Supergirl teamed up on the big screen, where Kara was played by Sasha Calle.

Initially three actresses have already tested for the role. Milly Alcock (The House of the Dragon), Emilia Jones (CODA), and Meg Donnelly (The Winchesters, Legion of Superheroes) auditioned for Supergirl, with Alcock being the one to don the cape moving forward.

On January 30, 2024, Gunn praised Alcock, saying:

Strangely, Milly was the FIRST person I brought up to Peter for this role, well over a year ago, when I had only read the comics. I was watching House of the Dragon & thought she might have the edge, grace & authenticity we needed for the DCU’s Supergirl. And now here we are. Life is wild sometimes.

When describing their version of Kara Zor-El, Gunn said:

“Superman was sent to Earth, and, and he was raised by incredibly loving parents, whereas Kara was in Krypton, she was on a piece of Krypton that drifted away from the planet, and lived there for the first 14 years of her life among [a] horrible situation where she watched everybody around her die. So she's a much harsher and more f—ked up Supergirl than we've been used to this far.”

Does 'Supergirl' Have a Release Date?

The Supergirl film does not have a release date, but we do have an idea of when it will hit theaters. James Gunn previously said that: “We'll have a Superman com[ing] out. And then two years later, we have Supergirl coming out.”

With Superman slated for July 11, 2025, that means Supergirl would release sometime in 2027.

Who Are the Creatives Behind 'Supergirl'?

As of now, the only people attached to the project are, of course, James Gunn, Peter Safran, and Tom King. Gunn confirmed that Ana Nogueira had written a script for the film. He posted on Threads praising her work, saying:

A hearty public welcome to Ana Nogueira to the DC Studios family. Ana is an amazing writer whose screenplay adaptation of Woman of Tomorrow is above and beyond anything I hoped it would be. We’re excited to be moving forward on this unique take on Supergirl in this beautiful, star-spanning tale.

The film still does not officially have a director, but it was reported that Craig Gillespie (I, Tonya) is in the running.

After an outlaw named Tom Chaney (Josh Brolin) murders her father, feisty 14-year-old farm girl Mattie Ross (Hailee Steinfeld) hires Rooster Cogburn (Jeff Bridges), a boozy, trigger-happy lawman, to help her find Chaney and avenge her father. The bickering duo is not alone in their quest because a Texas Ranger named LaBoeuf (Matt Damon) also tracks Chaney for his reasons. Together, the unlikely trio ventures into hostile territory to dispense some Old West justice.

Supergirl: Woman of Tomorrow is essentially True Grit in space. Ruthye is a young girl looking for revenge for her father, and Kara is the hero who reluctantly agrees to aid her on the journey.
