Milly Alcock's Supergirl Cape Uses Christopher Reeve Fabric—Stuns at Brazil World Cup Premiere

Australian actor Milly Alcock is taking flight from breakout TV sensation to silver-screen superhero, fronting Vogue Australia’s June 2026 issue just weeks before her headline debut in Supergirl: Woman of Tomorrow lands in cinemas on 26 June 2026. The 26-year-old Sydneysider—best known as young Rhaenyra Targaryen in HBO’s House of the Dragon—told Vogue she still finds the “weird and wonderful” responsibility of wearing the iconic S-shield overwhelming, yet thrilling, especially when she spots little girls already dressing as Supergirl. Director Craig Gillespie (I, Tonya) praises Alcock’s instinct for balancing grit and humour, calling her performance in the DC reboot “a beautiful mix of emotion and irreverence”. Production officially kicked off this month, with DC Studios confirming that Supergirl will soar into theatres and IMAX screens worldwide on 26 June 2026. Alcock’s athletic background—she grew up wrestling brothers and sending stunt-team bruise pics—helped her master the high-wire fight choreography and “space-Western” tone she hints will define the film. Beyond the cape, Alcock is capitalising on new-found global buzz by launching her own production company and eyeing indie collaborations that were “impossible to book” before Supergirl. She credits her single-mum upbringing and Newtown High School of the Performing Arts training for keeping her grounded amid rapid fame. With a Critics’ Choice nomination already under her belt and a blockbuster franchise on the horizon, Milly Alcock is positioning herself as Hollywood’s next home-grown powerhouse. Expect search interest—and box-office numbers—to skyrocket as the countdown to Supergirl: Woman of Tomorrow begins.
