Milly Alcock Landed Supergirl — Then Panic Set In
A single text made it official: House of the Dragon star Milly Alcock is the DCU’s Supergirl — and her first reaction was panic.
Milly Alcock got the text that every young actor dreams about: she was in as Supergirl for the new DCU. Her first reaction? Not exactly flying-high confidence. More like: wait, what did I just sign up for?
The panic phase (totally relatable)
Fresh off House of the Dragon, Alcock told Forbes Australia she spiraled a bit right after the confirmation text. She even called the movie’s director, Craig Gillespie, to say she wasn’t sure she could pull it off. Not the usual victory lap quote you expect when someone lands a superhero cape, but honestly, it tracks.
'I thought, "What have I done?" I really struggled to believe I could do it. I even called the director, saying, "I don’t know how to be that person. I’m just me."'
Then the reset
After the freak-out, she did the thing you have to do when the job is bigger than your nerves: trust your own taste and get to work. Alcock said she decided the only way through was to back herself and accept that timing isn’t always about feeling ready. It’s a clean, grown-up answer—and it sounds like she means it.
Fame, in waves
She also knows what this level-up means for her day-to-day life. The 25-year-old said London is chill for her right now; other places, less so. It comes and goes, but she’s fully aware that when Supergirl hits, the attention dial moves again.
What the movie looks like right now
- Title: Supergirl (based on the 'Woman of Tomorrow' comic series)
- Director: Craig Gillespie
- Release date: June 26, 2026 (theatrical)
- Cast: Milly Alcock; Matthias Schoenaerts; Eve Ridley; David Krumholtz; Emily Beecham; Jason Momoa as Lobo
So yeah—big cape, big jitters, big swing. If Alcock brings the same steel she had in Westeros to the DCU, Supergirl should be in very good hands.
