DC Studios announces Supergirl streaming debut on HBO Max with a dedicated American Sign Language version.

Theatrical performance for Supergirl was modest, with approximately $126 million worldwide, underscoring a weaker box office than Superman’s global haul (over $600 million).
In addition to Milly Alcock, the film features Jason Momoa portraying Lobo and David Corenswet reprising his role as Superman, expanding the film’s DC universe connections.
DC Studios is releasing Supergirl on physical media ahead of streaming, with 4K UHD, Blu-ray, and DVD set for September 8, 2026.
The film is directed by Craig Gillespie and will feature a fully signed American Sign Language edition led by Jonaz McMillian, with Catalene Sacchetti performing the signs, available on day one alongside the standard cut.
The release cadence includes a digital debut on September 10, 2026, followed by a linear HBO premiere on September 12, aligning with coverage that situates the project within a broader CW/TV integration history.
DC Studios is bringing "Supergirl" to HBO Max on September 10, 2026, with a special twist: a full American Sign Language version will premiere on the same day Cosmic Book News. The film, starring Milly Alcock as Kara Zor-El, struggled at the box office with just $126 million worldwide, but the streamer is banking on a broader audience through its dual-channel rollout—digital on September 10 and a linear HBO premiere on September 12 TVLine.
The ASL version was produced under the guidance of Jonaz McMillian, with Catalene Sacchetti performing the signs, marking DC's commitment to accessibility. Director Craig Gillespie's film, based on Tom King's "Supergirl: Woman of Tomorrow," also features Jason Momoa as Lobo and David Corenswet reprising his Superman role Superman Homepage.
"Supergirl" earned only $126 million globally after its June theatrical release. The film had a $38 million domestic opening and faced a sharp second-weekend drop and mixed reviews TVLine. With a reported production budget near $170–$186 million, the numbers fell far short of profitability and lagged far behind Superman's global haul of over $600 million TVLine.
DC Studios is using a coordinated rollout to recover from the theatrical shortfall. Physical media—4K UHD, Blu-ray, and DVD—drops September 8 Superman Homepage. The digital premiere follows two days later on September 10, then the linear HBO broadcast airs September 12 Cosmic Book News. This staggered approach keeps the film visible across multiple platforms and formats.
The streaming move centralizes the entire DC Universe on one platform, making it simpler for fans to watch the expanded universe together. The strategy reflects leadership's decision to prioritize long-term content dominance over theatrical-only releases TVLine.
The fully signed American Sign Language version launches alongside the standard cut on day one—not months later. Jonaz McMillian led the production with Catalene Sacchetti performing all signs, making the film accessible to deaf and hard-of-hearing audiences from the start Cosmic Book News. This move broadens the potential viewership beyond theater attendance and reflects a growing industry focus on inclusive entertainment.
Milly Alcock reprises her role as Kara Zor-El, continuing the character arc from last year's film TVLine. The cast also includes Jason Momoa as Lobo and David Corenswet returning as Superman, tying "Supergirl" directly into the larger DCU Superman Homepage. The September 2026 streaming premiere gives the film a second life and positions it within DC's broader multi-platform strategy.
