Milly Alcock Opens Up About Awkward Early Moment on HOUSE OF THE DRAGON: “We're Gonna Get You an Acting Coach”
Milly Alcock big breakout role was in House of the Dragon, and soon, we’ll be seeing her soar into the DC Universe as Supergirl. But it turns out her first days in Westeros weren’t quite the confidence boost you’d expect for someone destined to wear the cape of Kara Zor-El.
During a recent appearance on The Tonight Show with Jimmy Fallon, Alcock shared a brutally honest and funny story about what happened on just her second day filming the Game of Thrones prequel series.
“On my second day on House of the Dragon, one of the—I'm not gonna say who, but someone very high up—pulled me aside and was like, ‘Um, we're gonna get you an acting coach.”
Ouch. That would’ve been rough to hear as an actor. Alcock, who was already an award-winning actor in Australia thanks to her work on Upright, said the moment pretty much confirmed all her worst fears. She joked:
“It just confirmed everything that I’ve kind of known to be true, [which] is that I’m not very good at my job, You know what I mean! I was like, 'I can’t do this. This is terrible. This is a big mistake.’”
To his credit, Fallon quickly reassured her that her take on young Princess Rhaenyra was an instant fan-favorite. Alcock’s performance was one of the strongest and most memorable parts of House of the Dragon's first season, earning praise across the board.
Now, Alcock is stepping into the role of Supergirl in Supergirl: Woman of Tomorrow, directed by Craig Gillespie (Cruella, I, Tonya) and part of the newly rebooted DC Universe from James Gunn and Peter Safran.
According to the official synopsis, the film will follow Kara Zor-El on a wild intergalactic revenge mission after meeting a young girl named Ruthye (played by Eve Ridley), and yes—Krypto the Superdog will be along for the ride.
It’s based on the acclaimed comic series by Tom King and Bilquis Evely and is slated to hit theaters June 26, 2026.
