Many young actresses competed for the role of Supergirl in DC Universe, and Milly Alcock quickly emerged as one of the front-runners. After a tense audition process, House of the Dragon star was eventually cast as the next Kara Zor-El in James Gunn and Peter Safran’s new DC Universe.

Alcock starred in several Australian dramas throughout her teenage years, but it took a while before she got her big break. That moment finally came in 2022, when she played the young Princess Rhaenyra Targaryen in House of the Dragon and received a Critics’ Choice Award nod for her role.

Alcock has been searching for her next juicy role since Season 1 wrapped up, and she’s now gearing up for the biggest challenge of her career. She’ll play Kara Zor-El/Supergirl in the DC Universe, and she’s expected to appear in another DC-based project before leading her standalone movie Supergirl: Woman of Tomorrow.

This project is still in the early stages of development and it’s being written by Ana Nogueira. James Gunn previously described her adaptation as “above and beyond anything I hoped it would be.”

Alcock defeated the likes of Emilia Jones and Meg Donnelly to be cast as Supergirl, and it remains to be seen if she’ll make her debut in Superman: Legacy alongside David Corenswet.
