Supergirl 2026: Milly Alcock Stars in James Gunn-Produced DCU Film, and Power Woman Name Appears in Animated Series
The 2026 DC Universe (DCU) film Supergirl brings Kara Zor‑El, portrayed by Milly Alcock, onto the big screen for the first time in the new franchise. Directed by Craig Gillespie and written by Ana Nogueira, the picture is produced by James Gunn and Peter Safran of DC Studios. It follows the 2025 Superman film, the inaugural entry in DCU Chapter One: Gods and Monsters, and is slated for a U.S. theatrical release on June 26 2026 after a premiere in Brooklyn on June 22.
The story adapts the 2021‑22 comic miniseries Supergirl: Woman of Tomorrow by Tom King and Bilquis Evely. Alcock’s Kara is a Kryptonian who travels across the galaxy in search of vengeance, a plot that departs from the grounded origin presented in the 2023 film The Flash. The supporting cast features David Corenswet as Clark Kent, Eve Ridley, Matthias Schoenaerts, Emily Beecham, David Krumholtz, and Jason Momoa.
Production wrapped in early 2025 at Warner Bros. Studios Leavesden, London, and Scotland. The film’s release marks the second DCU feature after Superman and sits alongside Peacemaker and Creature Commandos within Chapter One’s broader slate.
While the live‑action film is a distinct venture, the animated series My Adventures with Superman has introduced a new superhero name for Kara in its third season. The Adult Swim series, launched in 2023, is not part of the DCU but shares the character’s name and thematic elements. In season 3, Kiana Madeira voices Supergirl, who is revealed to be Brainiac’s adopted daughter. After aiding Superman in defeating Brainiac, Kara contemplates adopting the moniker “Power Woman” to signal a fresh identity.
The “Power Woman” title echoes the Kingdom Come comics, where Kara Zor‑L is known by that name. Kingdom Come is an alternate‑future miniseries that explores a new generation of heroes confronting a weary older guard. James Gunn has cited Kingdom Come as an influence on the DCU’s visual and narrative direction, including the House of El crest that appears on the suits of Superman and Supergirl.
In My Adventures with Superman, the suggestion of a new name is a narrative moment rather than a marketing push. Writers such as Jake Wyatt have used the idea to examine Kara’s growth after her battle with Brainiac. The name does not replace the public’s use of “Supergirl,” but it highlights the character’s evolving self‑definition.
The DCU’s Chapter One: Gods and Monsters places a new generation of heroes at the core of its story arc. James Gunn’s 2025 Superman introduced a young Clark Kent who must reconcile his Kryptonian heritage with his human upbringing. The 2026 Supergirl continues that theme by presenting Kara as a distinct, mature hero who carries trauma from Krypton’s destruction.
Both the film and the animated series demonstrate the DCU’s strategy of blending comic‑book continuity with fresh storytelling. The use of the Kingdom Come motif—whether through the House of El crest or the “Power Woman” moniker—provides a connective thread for fans familiar with the comics while allowing new audiences to engage with the characters in contemporary contexts.
The release of Supergirl in June 2026 will add a second major DCU feature to the franchise’s schedule, following the July 2025 release of Superman. The film’s premiere in Brooklyn and subsequent U.S. theatrical release are part of Warner Bros. Pictures’ plan to roll out the DCU’s Chapter One slate over the next few years.
In summary, the 2026 Supergirl film introduces Milly Alcock’s Kara Zor‑El to the DCU’s cinematic universe, while the animated My Adventures with Superman season 3 explores the “Power Woman” name as a narrative exploration of Kara’s identity. Both projects reflect James Gunn’s ongoing use of Kingdom Come themes and the broader DCU goal of showcasing a new generation of heroes.
