Milly Alcock has won the role of Supergirl the DCU.
She will first appear in James Gunn’s ‘Superman: Legacy’.
The character will also lead ‘Supergirl: Woman of Tomorrow’.

James Gunn has found the person he wants to play Kara Zor-El –– AKA Supergirl, the superpowered young woman who is Superman’s cousin –– in ‘Supergirl: Woman of Tomorrow’.

Milly Alcock, best known for playing the young Princess Rhaenyra Targaryen in HBO’s first season of ‘Game of Thrones’ spinoff ‘House of the Dragon’, has landed the much-sought-after role in the DC Universe being overseen by Gunn and his fellow DCU boss/producer Peter Safran.

While such casting announcements –– this one came via The Wrap –– usually sit in the rumor sphere before the studio comments, Gunn has taken to Instagram to confirm Alcock’s presence in the DCU.

What is the plan for the Supergirl movie?

Once Supergirl has debuted in ‘Legacy’, she’ll then appear in her own movie, which was announced alongside the rest of Gunn and Safran’s plan for the first wave of their new movie/TV universe.

‘Supergirl: Woman of Tomorrow’ will be a big-scale sci-fi film based on Tom King and Bilquis Evely’s comic run. It features a “darker, harsher” version of Kara Zor-El raised on a surviving chunk of Krypton who sees everyone around her die.

This is what Gunn said at the time of the announcement:

“This is a very different type of Supergirl. In our film, we see the difference between Superman, who was sent to Earth and raised by loving parents from, you know, the time he’s an infant, versus Supergirl, who was raised on a rock chip-off of Krypton and watched everyone around her die and be killed in terrible ways for the first 14 years of her life, and then came to Earth when she was a young girl and is much more hardcore. She’s not exactly the Supergirl we’re used to seeing.”

Who else was in the running for Supergirl?

Emilia Jones in 'CODA'

Alcock got the role after an audition and a screen test, and the other two main contenders were Emilia Jones (who starred in Oscar winner ‘CODA’ and appeared in last year’s ‘Cat People’), and Meg Donnelly, known for the Disney ‘Zombies’ movies.

Donnelly also had some experience with Supergirl, as she has voiced the role in several animated DC outings.

When will we see Alcock as Supergirl in theaters?

‘Superman: Legacy’ has a release date scheduled for July 11th, 2025. Given that it has yet to find a director, the Supergirl movie has yet to lock in a date.
