Millie Alcock to Star in Old Vic's Miss Julie Revival

From cape to corset. Millie Alcock — fresh off her turn as Supergirl in the DC fold — has been tapped to play the title role in a new revival of Miss Julie at London’s Old Vic.

Variety reported the casting this week: Alcock will take on Julie in a modern adaptation of August Strindberg’s 1888 play. At its core, Miss Julie is a razor-sharp study of class, power and desire — an aristocrat’s daughter who, during her twenty-first birthday celebrations, sparks a dangerous liaison with one of her father’s servants. The consequences are anything but tidy.

Rebecca Frecknall, the Old Vic’s associate director, will both adapt and direct this staging. Her approach promises a contemporary edge that leans into the play’s emotional ferocity; expect intensity rather than period prettiness. The production opens on April 10, 2027 and runs through May, bringing a new wave of theatergoers into a story that’s still unsettlingly modern.

Why does this casting matter beyond the excitement of a high-profile crossover? Because Alcock isn’t just a screen presence; she’s a performer with stage chops. She’s already appeared in 2023’s production of The Crucible at the National Theatre, and viewers will recognize her from House of the Dragon — where she played a young Rhaenyra Targaryen — and the mini-series Sirens. This Old Vic turn will put her theatrical instincts front and center.

There’s also a film angle. Alcock is confirmed to appear as Supergirl/Kara Zor-El in Man of Tomorrow, slated for release on July 9, 2027. Beyond that, the landscape looks less certain: recent leadership changes at DC Studios have prompted questions about the future of the cinematic universe and the roles actors will continue to inhabit. Will she remain a cape-clad figure in future DC installments? Only time will tell.

This stage casting feels like a deliberate pivot: a chance for Alcock to deepen her craft and remind audiences she can anchor intimate, combustible drama as easily as blockbuster spectacle.

For now, theatergoers can look forward to a stripped-back, emotionally charged Miss Julie at one of London’s most storied venues, while film fans mark their calendars for Man of Tomorrow in July. Keep an eye on ticket announcements and casting updates — this is one performance that could shift how we see Millie Alcock, on stage and on screen.
