Earlier this month, Milly attended 2026 CinemaCon with Craig and with Lobo actor Jason Momoa who makes his debut as the DC character in the upcoming film.

She has also talked about some fears she has over her solo film debut as the iconic character. While she was well-received in last year’s Superman, this movie will be a solo venture for her.

“Of course I’m scared. Of course I want people to like me and the movie. But ultimately, it’s out of my control,” she told Vanity Fair in early April.

She also discussed how her time on House of the Dragon has prepared her. Read more here.

Supergirl will hit theaters on June 26. Watch the trailer!
