“Supergirl” soars to streaming on HBO Max on Sept. 10.
Milly Alcock, who previously reigned as Princess Rhaenyra Targaryen in HBO’s “House of the Dragon” and played Simone in Netflix’s 2025 limited series “Sirens,” took her stardom to the next level in her punk-rock take as “Supergirl.”
“Supergirl” arrived in theaters on June 26 a year after “Superman,” which rebooted the DC Universe under the direction of James Gunn and Peter Safran. Unlike its counterpart, “Supergirl” lost $100 million to $120 million in its theatrical run, debuting to a $37.1 million from 3,600 North American theaters and $62.6 million globally. It finished its run with just $126 million worldwide.
