‘Supergirl’ Trailer: Milly Alcock as Kara Zor-El. Watch teaser!

The DC Universe is soaring to new heights with the release of the first teaser trailer for Supergirl: Woman of Tomorrow, introducing Milly Alcock as the iconic Kryptonian hero Kara Zor-El.

Directed by Craig Gillespie and set to hit theaters on June 26, 2026, this film promises a fresh take on Superman's cousin, blending high-stakes action with a punk-rock edge that sets her apart from her more optimistic relative.

Alcock, best known for her breakout role in House of the Dragon, steps into the cape with a fierce, anti-heroic vibe, declaring in the trailer, "I, Kara Zor-El, hereby declare that 23 will be the best year yet."

The teaser opens with Kara crashing into the Fortress of Solitude, a nod to her Kryptonian roots, before unleashing a whirlwind of explosive sequences.

Viewers get glimpses of her tragic backstory—watching her home planet Krypton perish, including her parents, played by David Krumholtz as Zor-El—contrasting sharply with baby Kal-El's (Superman) escape.

The trailer highlights quick editing, pulsating music, and intense confrontations, including a showdown with Jason Momoa as the interstellar bounty hunter Lobo.

It's clear this Supergirl is no sidekick; she's a force of "truth, justice, whatever," embracing a grittier, more rebellious spirit.

James Gunn, co-head of DC Studios, has weighed in on the project, emphasizing how Alcock's portrayal differentiates Kara from Superman.

"Kara had to watch everyone around her die," Gunn noted, underscoring the character's emotional depth and survivalist mentality.

The film, based on Tom King's acclaimed comic run, follows Kara on a cosmic journey of vengeance and self-discovery, accompanied by her loyal dog Krypto and a young girl named Ruthye.

Fan reactions on social media have been electric, with many praising Alcock's casting and the trailer's high-energy style.

One user called it "promising," hoping Alcock becomes Hollywood's next big star, while others shared stills and clips buzzing with excitement.

Even Alcock herself reacted with raw enthusiasm at a preview event: "It's gonna happen.

Shit!"

This installment comes hot on the heels of 2025's Superman film, solidifying the rebooted DCU under Gunn and Peter Safran's vision.

With a screenplay by Ana Nogueira, Supergirl: Woman of Tomorrow looks poised to deliver a blockbuster blend of heart, humor, and heroism.
