Capes look great on a poster. Earning one is another story. That’s how Milly Alcock got her toughest assignment yet, because playing the Girl of Steel in Supergirl meant months of physical prep before a single frame was shot. The good news? She told us the whole thing was easier than she feared. Not easy. Easier.
How Milly Alcock Got Battle-Ready
Here’s the thing about how Alcock prepared. She didn’t wait. Stunt work was always going to be part of the job, so she started training long before cameras rolled. Smart move. Milly Alcock’s preparation was structured so carefully that nothing ever piled up on her. What she expected to be a grind turned out to be, in her words, less of a challenge than she’d imagined.
How Alcock got ready wasn’t a solo act, either. Productions this size come with an army of stunt coordinators and trainers, and she leaned on all of them. By the first day of shooting, the choreography was muscle memory. Watch the fight scenes and you can tell.
How Alcock Got From Westeros to Krypton
Most people met Alcock as young Rhaenyra Targaryen on House of the Dragon. That performance put her on the radar of James Gunn and Peter Safran, the two executives rebuilding the DC Universe from scratch. First came a quick appearance in last summer’s Superman. Then the big one. Her own movie, her own cape, as Kara Zor-El.
And her Kara is different. Rougher. This version of the character carries scars her famous cousin never had, and critics noticed. Reviews of the film have been mixed, sure. But Alcock herself keeps getting singled out as the best thing in it. One major critic praised her hard-edged, punky take on the hero. All that preparation went somewhere.
A Revenge Story With a Space Dog
Craig Gillespie directs, which tells you something about how the actress got in shape for this ride. The filmmaker behind I, Tonya and Cruella doesn’t do standard-issue anything, and his action demands real prep. Working from a script by Ana Nogueira, based on Tom King’s comic Woman of Tomorrow, he sends Kara tearing across the galaxy to hunt down the villain who hurt her dog Krypto. A superhero revenge movie about a space dog. Somehow, it works.
The supporting cast helps. Jason Momoa shows up as Lobo, the intergalactic biker fans have begged to see on screen for decades. Matthias Schoenaerts, Eve Ridley, David Krumholtz, and Emily Beecham fill out the roster, while David Corenswet drops in as Superman to tie it all to the bigger DCU. There’s more coming, too. Alcock is expected to figure heavily into next year’s Man of Tomorrow and beyond.
How Milly Alcock Got Here Says Everything
Strip away the cape and the wire rigs, and the story of how Milly Alcock trained for this role is pretty simple. Start early. Trust the team. Treat the physical stuff like any other part of the craft. That’s it. No secret, just work done in the right order. And for a character who spends half the movie brawling her way across alien bars, the difference shows in every frame.
