Supergirl (2026) – Milly Alcock Takes Flight: DC’s Next Big Hero Movie Preview

The DC Universe (DCU) is expanding at warp speed, and Supergirl is set to soar as one of the most anticipated films of 2026. Starring Milly Alcock (known for her breakout role as young Rhaenyra Targaryen in House of the Dragon) as Kara Zor-El / Supergirl, this standalone adventure marks the second major feature in James Gunn and Peter Safran’s rebooted DCU, following the 2025 Superman. With principal photography wrapped in mid-2025 and post-production underway, the film is primed for its theatrical debut on June 26, 2026, in IMAX and premium formats via Warner Bros. Pictures.

This version of Supergirl promises a bold, cosmic departure from previous portrayals. Drawing inspiration from Tom King’s acclaimed 2021–2022 comic miniseries Supergirl: Woman of Tomorrow (illustrated by Bilquis Evely), the story delivers a grittier, more emotionally complex Kara — a jaded survivor shaped by trauma rather than the optimistic, Earth-raised hero fans might expect.

A Darker, Cosmic Origin for Kara Zor-El

Unlike her cousin Kal-El (Superman), who arrived on Earth as an infant and was raised by loving adoptive parents, Kara spent her first 14 years on a surviving fragment of Krypton, witnessing death and destruction all around her. This upbringing has left her hardened, cynical, and more likely to seek out red-sun planets where she can let loose (and even get drunk) without her powers. James Gunn has emphasized this contrast: Superman sees “the good in everyone,” while Supergirl sees “the truth.”

The plot follows Kara celebrating her 23rd birthday by traveling the galaxy with her loyal super-dog Krypto. She crosses paths with young alien girl Ruthye Marye Knoll (Eve Ridley), who recruits her for a vengeful quest against Krem of the Yellow Hills (Matthias Schoenaerts), the marauder who murdered Ruthye’s father. What begins as a reluctant team-up evolves into an interstellar journey of revenge, self-discovery, and moral reckoning — blending high-octane action, space opera vibes, and deep character exploration.

Here are some stunning first-look images of Milly Alcock as Supergirl in her battle-worn, sleek costume — note the enlarged “S” symbol, golden belt details, and practical cape that show wear from her rougher adventures:

These shots highlight the suit’s more rugged, lived-in design compared to Superman’s pristine look, emphasizing Kara’s tougher lifestyle.

Stellar Cast & Creative Team

• Milly Alcock as Kara Zor-El / Supergirl — Gunn called her “the best bit of casting I’ve ever done,” praising her mix of vulnerability, humor, and strength.
• Eve Ridley as Ruthye Marye Knoll — The determined young girl who sets the revenge plot in motion.
• Matthias Schoenaerts as Krem of the Yellow Hills — The ruthless antagonist.
• Jason Momoa as Lobo — Making his DCU debut as the iconic bounty hunter in a role teased heavily in trailers (likely a key supporting part with plenty of chaotic energy).
• David Krumholtz as Zor-El and Emily Beecham as Alura In-Ze — Kara’s Kryptonian parents.
• David Corenswet reprises Superman (Kal-El) in a supporting/cameo role, as confirmed by Alcock.

Directed by Craig Gillespie (I, Tonya, Cruella) from a script by Ana Nogueira, the film features practical effects, cosmic scale, and Gunn’s signature blend of heart and humor. The teaser trailer (released December 2025) and full trailer have racked up massive views, showcasing Krypton’s remnants, galactic travels, heat-vision blasts, and Lobo’s wild antics. A recent January 2026 first-look image via USA Today gave fans an even closer view of Alcock suited up.

3. Milly Alcock’s Star Power — Her acclaimed performance in House of the Dragon makes her a perfect fit for Kara’s complexity.
