Directed by Craig Gillespie and written by Ana Nogueira, Supergirl is the second theatrical film in James Gunn’s DC Universe and adapts Tom King and Bilquis Evely’s Supergirl: Woman of Tomorrow comic. Milly Alcock stars as Kara Zor-El, with the film releasing June 26, 2026. Unlike her cousin Superman, Kara grew up on a chunk of Krypton, watching everyone around her die for the first 14 years of her life, which makes her more jaded and traumatized.
The story begins as Kara celebrates her 21st birthday traveling across the galaxy with Krypto the Superdog. Because she deliberately visits planets with red suns to depower herself, she spends much of her time drinking in dive bars to cope with her loss and trauma. Her drifting ends when she meets a young alien girl named Ruthye Marye Knoll, portrayed by Eve Ridley. Ruthye’s father was murdered by Krem of the Yellow Hills, played by Matthias Schoenaerts, and she asks Kara for help getting revenge.
Kara reluctantly agrees, joining Ruthye on an interstellar road trip of “vengeance and justice”. The quest turns personal when Krem poisons Krypto during an encounter, and the only antidote is in Krem’s possession. To save her dog, Kara must hunt Krem across hostile worlds, giving the film its ticking-clock urgency. Along the way she confronts alien raiders, battles in war-torn cities, and even faces a near-death in space before flying into a sun to recharge.
The journey introduces Jason Momoa as Lobo, the interstellar bounty hunter who recognizes Kara “from the dive bar” and becomes an uneasy ally. David Corenswet also appears as Superman, underscoring Kara’s contrast to “the freaking nerd who sees the good in everyone” while she “sees the truth”. Flashbacks reveal Kara’s parents, Zor-El and Alura, played by David Krumholtz and Emily Beecham. The film’s tone is described as darker, edgier, and more cosmic than Superman’s story — a “space western” about grief, survival, and found family.
Ultimately, Kara’s mission with Ruthye forces her to confront what it means to be Kryptonian without a home world. The official tagline is “Find your place in the universe”. After saving Krypto and helping Ruthye get justice, Kara begins to define herself outside her trauma, setting her up for her next DCU appearance in Man of Tomorrow.
