Supergirl star Milly Alcock says the new DC Studios comic book movie humanises its hero.

The Australian actor, who takes on the dual role of Supergirl/Kara Zor-El, joined cast members Jason ​Momoa, Eve Ridley and Matthias Schoenaerts at a UK sneak peek fan event in London ‌on Thursday, teasing an unexpected turn on the big screen.

“I would describe her as a very reluctant hero. I think she’s a bit of a rebel, but she’s got a lot of humility, and I think audiences are going to ​be very surprised,” Alcock said.

Landing the lead role in the summer blockbuster took the House of the ​Dragon and Sirens actor, 26, on an empowering and emotion-filled journey.

“It’s my first film, so ⁠it’s kind of been the biggest thing ever in the world. And I feel like now I ​can do anything because I’ve done something like this,” Alcock said. “It was like every feeling at once, the ​highest highs and the lowest lows. It’s a beautiful sea of bliss and self-doubt.”
