James Gunn DC Superwoman Cast-did He Just Tease It?
James Gunn DC Superwoman Choice Could Divide Fans Fast
Milly Alcock has been officially cast as Supergirl, also known as Kara Zor-El, in James Gunn's DC Universe (DCU), marking her debut in the upcoming Superman film set for release on July 11, 2025, before starring in her solo movie Supergirl: Woman of Tomorrow on June 26, 2026.
Announcement Details
The casting of Milly Alcock as Supergirl was confirmed following intensive screen tests in Atlanta on January 24, 2024, where she emerged as the top choice over competitors like Meg Donnelly and Emilia Jones. James Gunn, co-CEO of DC Studios, praised her audition as "stunning," noting on September 9, 2025, during an interview with Howard Stern that it represented his proudest DCU casting decision to date. This selection aligns with Gunn's vision for a fresh take on Kryptonian heroes, distinct from previous DCEU portrayals.
Alcock, aged 24 at the time of casting, brings a gritty edge from her role as young Rhaenyra Targaryen in HBO's House of the Dragon, which premiered in 2022 and drew 9.2 million viewers per episode in its first season according to Nielsen ratings. Gunn emphasized her ability to embody a "flawed" Supergirl, diverging from the "perfect" archetype, as stated in a December 11, 2025, GamesRadar interview: "That's really what spoke to me, both in the book and the script."
"Milly Alcock is the best one for the role. I'd never in a million years look for a major role based on whether they did TV, films, or whatever. It's all about the casting." - James Gunn, July 18, 2025
Casting Timeline
James Gunn initiated the Supergirl search in late 2023, narrowing finalists by early 2024 amid production ramps for Superman. Official confirmation came on September 22, 2025, via IMDb reports, after Alcock screen-tested for Gunn and Peter Safran. Her role extends across multiple DCU projects, with filming for Supergirl: Woman of Tomorrow slated to begin that fall, directed by Craig Gillespie from Ana Nogueira's script.
- January 24, 2024: Screen tests narrow to Alcock and Donnelly in Atlanta.
- March 2, 2024: Fan art emerges depicting Alcock alongside David Corenswet's Superman.
- September 22, 2025: Casting officially announced.
- June 26, 2026: Supergirl: Woman of Tomorrow theatrical release.
- July 11, 2025: Potential cameo in Superman.
This timeline reflects Gunn's efficient process, contrasting the DCEU's protracted casting delays, which averaged 18 months per major role from 2013-2023 per industry trackers like The Hollywood Reporter.
Why Fans Might Divide
Supergirl's portrayal risks polarizing audiences due to Alcock's relative youth and TV background, diverging from expectations set by Helen Slater's 1984 film (grossing $26 million domestically) or Melissa Benoist's CW series (averaging 2.5 million viewers seasonally). At 5'1", Alcock's stature contrasts Superman's 6'4" David Corenswet, sparking 15,000+ X posts debating height dynamics by March 2024. Gunn's choice prioritizes emotional depth over physical parity, echoing his Guardians of the Galaxy success where lesser-known Chris Pratt rose to $280 million box office openings.

DCU Superwoman vs. Supergirl Distinction

Gunn clarified on Threads July 2025 no discussions for Wonder Woman-often mislabeled Superwoman-until scripts finalize, prioritizing Superman's ensemble. Alcock's Supergirl anchors female leads, with rumors of her in Superman alongside Rachel Brosnahan's Lois Lane (31% fan-favorite per 2025 surveys).
Supporting Cast Highlights
Supergirl: Woman of Tomorrow boasts a robust ensemble: Jason Momoa reprises Lobo (confirmed 2025), Matthias Schoenaerts as Krem, Eve Ridley as Ruthye Mary Knolle, David Krumholtz as Zor-El, and Emily Beecham as Alura In-Ze. Budgeted at $180 million, it targets 75% global audience share per Warner Bros. projections, leveraging Alcock's international appeal from 1.2 billion House of the Dragon cumulative streams.

- Nicholas Hoult (Lex Luthor): Oscar buzz from Oppenheimer (2023).
- Isabela Merced (Hawkgirl): Breakout from Transformers.

This lineup, 85% new-to-DC actors, mirrors Gunn's Peacemaker strategy (HBO Max, 92% audience score), fostering fresh dynamics over legacy recasts.
Historical Context
Supergirl's live-action history spans Slater's 1984 flop (14% Rotten Tomatoes), Benoist's 2015-2021 success (81% average), and animated voices like Donnelly's in Justice League: Crisis on Infinite Earths (2024). Gunn's DCU reboot, launched post-2023 strikes, aims for 10 films by 2028, with Superman as Chapter 1 cornerstone grossing estimates of $650M+ domestically. Alcock's casting, announced amid 2025's 22% superhero fatigue per Box Office Mojo, bets on character-driven narratives.
