So, you just watched the multiverse explode on screen and you’re wondering who played Supergirl in The Flash. The face behind the red cape is Sasha Calle, and honestly, her journey into the DC Universe is just as wild as the movie itself.
She isn't your typical Girl of Steel. If you grew up watching the CW or reading the classic comics, you probably expected a bubbly, blonde Kara Zor-El. Instead, Calle gave us something gritier. Something darker. She stepped into a role that felt heavy, literally and figuratively, playing a version of the character that had been locked in a Siberian bunker for years.
Why Sasha Calle’s Supergirl Felt Different
Before landing this massive gig, Calle was mostly known for her work on The Young and the Restless. Making the jump from daytime soap operas to a $200 million blockbuster is basically winning the lottery, but she earned it. Director Andy Muschietti famously shared the video of her finding out she got the part, and her reaction—pure, unfiltered tears—went viral.
She made history as the first Latina to play Supergirl. That’s a big deal.

In the film, she isn't just a sidekick. She’s the powerhouse. While Ezra Miller’s Barry Allen is busy tripping over time, Calle’s Kara is the one actually throwing down with General Zod. Her look—the short, dark hair and the intense, brooding stare—was actually inspired by the Injustice comics version of Superman’s daughter, Lara Lane-Kent, though she is still technically playing Kara Zor-El.
The Flash Movie: A Brutal Introduction
If you haven't seen it yet, or if you're just refreshing your memory, her introduction is pretty grim. In this alternate timeline, Barry Allen realizes that Superman never made it to Earth. Or rather, he did, but things went south fast.
Instead of a farm in Kansas, the Kryptonian pod was intercepted. Kara spent her life as a prisoner, used as a lab rat. By the time Barry and a retired Bruce Wayne (Michael Keaton) find her, she’s understandably "done" with humanity.

- The Powerhouse Factor: Even though she's been deprived of sunlight, once she gets a hit of those yellow solar rays, she’s terrifying.
- The Fighting Style: Calle did a ton of her own stunts. She described the experience as "visceral." You can see it in the way she fights; there’s a raw desperation there that you don’t usually see in Superman movies.
- The Emotional Core: Despite the lack of lines compared to the two Barrys, she managed to make people care about a character who had lost literally everything.
What Really Happened With Sasha Calle’s Future?
Here is where things get a little messy and, frankly, kind of sad for fans of her performance. When Sasha Calle was cast, the old DC regime had big plans. She was supposed to be the "new" permanent Supergirl for the franchise. There were even rumors and early talks about a solo film.
Then everything changed.
James Gunn and Peter Safran took over DC Studios and decided to hit the hard reset button. Because The Flash was a bit of a box office disaster and the "old" universe was being scrapped, Calle’s version of the character was caught in the crossfire.

In January 2024, it was officially announced that Milly Alcock (from House of the Dragon) would be taking over the role for the new DCU, starting with Supergirl: Woman of Tomorrow. Calle has been vocal about how "heartbroken" she was to lose the role, especially since she had a multi-picture contract. She really loved playing Kara.
Why Her Performance Still Matters
Even though she won't be back for the 2026 Supergirl movie, what Sasha Calle did in The Flash shouldn't be ignored. She broke the mold. She showed that Supergirl could be "edgy" and "rock & roll" without losing the character's soul.
Fans on Reddit and social media still post about her suit—which many argue is the best live-action Supergirl costume ever made. It stayed away from the "skirt and boots" look and went for something that felt like actual Kryptonian armor.
Is she gone for good? In the world of comic book movies, "never" is a dangerous word. With the multiverse now a standard plot device, there is always a tiny, 1% chance she could pop up as a variant or as Power Girl down the line. But for now, her time in the sun was short, bright, and unfortunately tied to a very complicated movie.
Actionable Insights for Fans
If you loved her performance and want to see what's next for the actress or the character, here is how you can stay in the loop:
- Watch "In the Summers": This was Calle's follow-up project after The Flash. It’s an indie drama that won big at Sundance, and it shows off her acting range away from the green screens and capes.
- Read "Supergirl: Woman of Tomorrow": This is the comic book by Tom King that the next movie is based on. If you liked the "warrior" vibe Calle brought, you’ll love this book. It’s arguably the best Supergirl story ever written.
- Track the New DCU: Keep an eye out for Milly Alcock’s debut in the upcoming Superman film (2025). It will be interesting to see how the "new" Supergirl compares to the grit Calle established.
- Follow the Stunt Work: If you’re into behind-the-scenes stuff, look up the stunt coordinators for The Flash. They’ve released clips of Calle’s training that show just how much work went into that Siberia breakout scene.
