When can you stream Supergirl on HBO Max?
HBO has set a global streaming debut exclusively on HBO Max for Thursday, Sept. 10, 2026, Deadline reports. Variety likewise says the film arrives on the service that day after a June theatrical opening.
HBO’s linear channel will play the movie two days later, on Saturday, Sept. 12, at 8 p.m. ET. Deadline says an ASL version, performed by Catalene Sacchetti and directed by Jonaz McMillan of The Pitt with ASL, streams exclusively on HBO Max that Saturday. CNET instead says the ASL cut arrives the same day as the Sept. 10 streaming launch. Both outlets agree that version is HBO Max exclusive.
CNET says viewers need a monthly or annual HBO Max subscription. The ad-based plan costs $11 a month; ad-free Standard is $18.50 and Premium is $23. CNET also mentions a Max, Hulu, and Disney Plus bundle as extra value, without quoting a current bundle price.
Who stars in the DC Studios movie?
Milly Alcock plays Kara Zor-El. Variety notes her prior work as Princess Rhaenyra Targaryen in HBO’s House of the Dragon and as Simone in Netflix’s 2025 limited series Sirens. Deadline lists co-stars Matthias Schoenaerts, Eve Ridley, David Krumholtz, Emily Beecham, David Corenswet, and Jason Momoa.
CNET identifies Ridley as Ruthye, Corenswet as Superman, Schoenaerts as Krem of the Yellow Hills, and Momoa as the immortal bounty hunter Lobo. Craig Gillespie directed from a screenplay by Ana Nogueira. DC Studios chiefs Peter Safran and James Gunn produced. Deadline says Nigel Gostelow, Chantal Nong Vo, and Lars P. Winther executive produced, with the character based on creations by Jerry Siegel and Joe Shuster.
Variety says the movie adapts Tom King’s comic Supergirl: Woman of Tomorrow, in which Supergirl and a young alien, Ruthye, hunt Krem of the Yellow Hill after he murders Ruthye’s father. Deadline’s synopsis follows Kara, cousin of Kal-El, on an interstellar journey of vengeance and justice after an adversary strikes too close to home, including a bid to save her dog, Krypto.
Why did the theatrical run matter for this streaming window?
Supergirl arrived in theaters on June 26, a year after Superman rebooted the DC Universe, Variety reports. It opened to $37.1 million from 3,600 North American theaters and $62.6 million globally, then closed at $126 million worldwide. Variety estimates the theatrical run lost $100 million to $120 million.
Safran told the New York Times, as quoted by Variety: “While ‘Supergirl’ didn’t meet our box office expectations, it’s just one component of a broader, long-term strategy at DC Studios that we remain confident in.” Variety adds that Rotten Tomatoes scored the film “rotten” and CinemaScore graded it B-minus. Streaming now gives subscribers another way to see Alcock’s take, a notable beat in celebrity breaking news around the new DC slate.
