Milly Alcock found out she was cast as Supergirl when the DC superhero movie's co-producer James Gunn sent her a text message with a link to an article announcing she had landed the coveted role. That was in January 2024.

"I just got a text from you. No one called me to say, 'You got the job.' It was just a text with a link," said the 25-year-old Australian actress.

"I tried calling you, but you did not pick up your phone," DC Studios' co-chairman and co-chief executive Gunn, 59, protested.

The American filmmaker and Alcock were at a Dec 8 virtual press conference ahead of the launch of Supergirl's teaser trailer on Dec 12. They were joined by Australian director Craig Gillespie, who helms the movie set to premiere on June 25, 2026.

Supergirl made a cameo at the end of Gunn's Superman (2025), when she showed up at Superman's abode, the Fortress of Solitude. She was introduced as the party-loving cousin of Kal-El, also known as Superman (David Corenswet) and the owner of Krypto the superdog.

Alcock knew she was going to be Kara Zor-El, the Maiden of Might, after her screen test.
