'House of the Dragon' star Milly Alcock is the new 'Supergirl'

Australian actress Milly Alcock, who played the young Rhaenyra Targaryen in the first season of HBO's "House of the Dragon," is the new Woman of Steel in the new DC Universe.

In a report by Variety, Alcock is set to headline the upcoming DC Studios feature film "Supergirl: Woman of Tomorrow," spearheaded by DC Studios CEO and co-CEO James Gunn and Peter Safran.

"She's not exactly the Supergirl we're used to seeing," Gunn said during the presentation of the first 10 titles in the new DCU slate.

The new feature film will be based on the DC comics run of the same name by Tom King and Bilquis Evely.

"Supergirl" follows Kara Zor-El's (Supergirl) story and her darker origin before she finally made her way to Earth.

Before her breakout role on HBO's "Game of Throne" prequel series, Alcock started her acting career as a teenager on Aussie TV.
