Becoming a Kryptonian superhero isn’t just about a cape — it’s months of sweat, fear, and a whole new language. Milly Alcock, who plays Kara Zor-El in the upcoming Supergirl film, just opened up about how terrifying — and transformative — that journey was.
Two months before cameras rolled, Alcock began daily two-hour stunt sessions. “I was so nervous,” she admitted, crediting her stunt team for rebuilding her confidence “piece by piece.” On top of dodging danger-filled choreography, she also had to learn Kryptonian dialect and master a grounded, slightly imperfect voice for Kara — since the character only started speaking English as a teenager.
She even shared a fun behind-the-scenes moment about filming an emotional Kryptonian-language scene with co-star David Krumholtz, who plays her on-screen father — calling him “such a soldier” for handling the heavy dialogue.
