Milly Alcock Opens Up About Terrifying SUPERGRIL Screen Test - “I Thought I Was Going to Vomit”
Suited up in red and blue, standing under hot lights, next to another hopeful contender, it’s not exactly a relaxing walk in the Fortress of Solitude.
In a recent interview with Elle.com, Supergirl: Woman of Tomorrow star Milly Alcock opened up about the nerve-wracking screen test that landed her the job, and it sounds like it was a pretty intense experience for her.
Alcock, who rocketed into the spotlight with House of the Dragon and is currently promoting her new Netflix series Sirens, has mostly stayed tight-lipped about her role as Kara Zor-El. But she finally gave fans a peek behind the curtain, saying:
“During a screen test, you’re in a room with all the other women [vying for the same part] and you’re all dressed as the character. [The studio] will get you lined up in the makeup truck and put the same makeup on you all and then test you on a stage.
“For Supergirl, it was myself and another girl. It was really scary; I thought I was going to vomit! But it’s just fear! That’s what happens! This job has been a journey of overcoming my own fear.”
Landing the part didn’t immediately feel like a triumphant victory either. Alcock said:
“I was kind of in disbelief. I was initially like, ‘What have I done?’ I then invited all my friends over to the house and we drank champagne.”
That blend of anxiety, disbelief, and celebration must’ve been a wild expericnce. Woman of Tomorrow promises a harder-edged Kara Zor-El, someone who’s been through hell before she even sets foot on Earth.
James Gunn described her as “much more hardcore,” contrasting her with her cousin Superman, who had the benefit of a loving Earth upbringing.
The movie, based on Tom King’s acclaimed 2022 comic, will follow Kara as she takes a cosmic journey with Krypto the Superdog to celebrate her 21st birthday, only to get tangled up with a girl named Ruthye and a brutal revenge mission.
The cast includes 3 Body Problem's Eve Ridley as Ruthye, Matthias Schoenaerts as the villain Krem, and Aquaman’s Jason Momoa as Lobo. Most recently, David Krumholtz and Emily Beecham joined the crew as Kara’s Kryptonian parents, Zor-El and Alura.
Supergirl: Woman of Tomorrow hits theaters June 26, 2026, and I’m very curious to see what’s in store for this DC movie.
