Milly Alcock flies to her next role amid a major shake-up at DC Studios.

The news broke earlier this week of Peter Safran and James Gunn's DC exit, with the duo no longer running the studio in the aftermath of the Warner Bros. Discovery and Paramount merger. While Gunn and Safran will continue their work on the upcoming Man of Tomorrow and their other projects already in production, with Jeremy Latcham now in charge, it is unclear what will become of the DC Universe from the past couple of years, in which Alcock has played a prominent role as Supergirl/Kara Zor-El.

Two days after the change in DC leadership was announced, Variety reported that Alcock has been cast in an adaptation of August Strindberg's play Miss Julie at London's Old Vic theater, premiering on April 10 and running through May. The Supergirl star is playing Miss Julie, who in the original Swedish play from 1888, is an aristocrat's daughter drawn to one of the family's married servants.

The new production is a modern take on the story adapted and directed by Old Vic associate director Rebecca Frecknall, and was originally produced at the International Theater Amsterdam. Check out the logline for the production below:

Stumbling into the kitchen on the night of her 21st birthday party, Julie seeks out her father’s employees John and Christine. As one room becomes a battlefield of class and sexual politics, a reckless flirtation becomes a merciless contest sending all three people hurtling towards destruction.

Miss Julie is Alcock's first role since her DCU movie was released earlier this year. While she received praise for her performance as the titular character, reviews for Supergirl were mixed, leading to a 52% critics' score and 72% audience score. At the box office, it grossed $126.5 million after being made on a reported production budget of $170 million.

Alcock will play Supergirl at least once more, as she is confirmed to be in Man of Tomorrow, which wrapped filming over the summer and will debut in theaters on July 9. Since she appears at the end of Superman, and her cousin is in Supergirl, this will be the third DCU movie featuring both characters, who have been critical to the universe's narrative so far.

What's unclear now is whether Latcham and parent company Skydance intend to completely reboot DC again or if they will retain actors, stories, and continuity from the universe Gunn and Safran have been building. The former indicates that Man of Tomorrow will be the last time Alcock plays Supergirl, but the latter option means that she could remain part of whatever the next iteration of DC looks like under the new leadership.

This question applies to all DCU characters from the past couple of years as well, including Superman/Clark Kent (David Corenswet), Lois Lane (Rachel Brosnahan), Lex Luthor (Nicholas Hoult), Peacemaker/Christopher Smith (John Cena), John Stewart (Aaron Pierre), and Guy Gardner (Nathan Fillion).

Outside of playing Supergirl in the DCU, Milly Alcock is known for her roles as young Rhaenyra Targaryen in HBO's Game of Thrones prequel House of the Dragon and Simone DeWitt in the Netflix miniseries Sirens. On the stage, she portrayed Abigail Williams in a 2023 production of The Crucible at London's National Theatre.
