Supergirl: Woman of Tomorrow (2026) — Full Movie Review, Cast, Plot & DCU Future

Released: June 26, 2026 | Director: Craig Gillespie | Rating: PG-13 | Runtime: 108 minutes | Studio: Warner Bros. / DC Studios

The DC Universe just launched its second major chapter, and this time, the spotlight belongs entirely to Superman's cousin. Supergirl: Woman of Tomorrow (2026) arrives with enormous expectations — not just as a standalone superhero film, but as a defining moment for how James Gunn's revamped DCU treats its female leads. Does it soar to legendary heights, or does it stumble before takeoff? We break it all down in this comprehensive, spoiler-aware review.

What Is Supergirl: Woman of Tomorrow About?

Before diving into the review itself, it helps to understand what kind of film this actually is. Many casual moviegoers expect a typical superhero origin story with city-saving battles and a villain threatening humanity. Supergirl 2026 is something very different. It's a raw, intimate revenge western set across nine alien worlds — closer in spirit to True Grit or Logan than to The Avengers.

The story centers on Kara Zor-El (Milly Alcock), a Kryptonian who was a teenager when her home planet was destroyed. Unlike her cousin Clark Kent / Superman, who arrived on Earth as an infant and grew up shielded from that loss, Kara lived through the trauma firsthand. She remembers her family, her people, her home — and she has been quietly falling apart ever since.

When the film opens, Kara is celebrating her birthday the only way she knows how: getting drunk on planets with red suns, where her powers are stripped away and she can actually feel something — even if that something is just ordinary vulnerability. During one of these self-destructive benders, she crosses paths with Ruthye Marye Knoll (Eve Ridley), a fiercely determined young girl whose entire family was massacred by the brutal space criminal Krem of the Yellow Hills (Matthias Schoenaerts).

Ruthye is hunting for justice. Kara wants nothing to do with it — until she is forced to. What follows is an interstellar road movie about grief, identity, and the slow, painful process of becoming a hero not because you were destined to, but because you chose to.

The Source Material: Tom King's Acclaimed Comic Run:

The film adapts the 2021–22 eight-issue comic miniseries Supergirl: Woman of Tomorrow by writer Tom King and artist Bilquis Evely. The comic was a critically beloved reimagining of Kara Zor-El that stripped away the cheerful "female Superman" trope and replaced it with a deeply traumatized, morally complex survivor.

King's original pitch reportedly featured a Supergirl and Lobo team-up modeled closely on the Mattie Ross and Rooster Cogburn dynamic from True Grit (1968). That DNA made it into the final film — you can feel the Western influence in nearly every scene.

The source material was so beloved that when DC Studios announced the adaptation in January 2023, copies sold out on Amazon and in comic shops within days. That's the level of fan enthusiasm surrounding this project.

Milly Alcock as Kara Zor-El / Supergirl:

This is the role that will define Milly Alcock's career. Already known to millions as the young Rhaenyra Targaryen in HBO's House of the Dragon, Alcock was cast as Supergirl in January 2024, first appearing briefly in 2025's Superman before leading her own film here.

Her performance is the undisputed best thing about the movie. Alcock brings genuine weight to Kara's emotional armor — the sarcasm, the recklessness, the casual cruelty toward others that masks deep, unprocessed pain. When the film asks her to be tender, particularly in the Krypton flashback sequences, she delivers something genuinely moving. This is not a one-note performance. It is a deeply considered portrait of a young woman who has survived something catastrophic and has no healthy way to process it.

Eve Ridley as Ruthye :

Ridley matches Alcock beat-for-beat as the relentlessly earnest Ruthye. The "gruff adult + determined child" dynamic is well-trodden genre territory, but both actresses do their best to make it feel fresh.

Matthias Schoenaerts as Krem :

Schoenaerts brings cold menace to the film's primary villain, though critics note that Krem feels somewhat underwritten beyond his role as a catalyst for the plot.

Jason Momoa as Lobo :

Perhaps the most talked-about casting choice: Momoa, previously Aquaman under the old DCEU, reinvents himself as the anarchic space mercenary Lobo. Critics agree he's perfectly suited for the role — but many point out that Lobo feels shoehorned into a story where he doesn't organically belong. He is not a character in the original Woman of Tomorrow comic. His inclusion seems designed primarily to establish the character for future DCU use.

Director's Vision: Craig Gillespie's Take on a Superhero Western :

Craig Gillespie (I, Tonya, Cruella, Pam & Tommy) is a director known for stylized biopics and character studies. He brings that sensibility here — focusing less on grand spectacle and more on Kara's internal emotional journey.

Gillespie described the film as a "road movie" with a "darker tone than Superman" because the story required candidly confronting Kara's childhood trauma. He estimated that nine distinct alien worlds were featured, each with unique languages and environments, giving the film a genuinely expansive science-fiction scope.

One notable directorial choice: Kara does not don her iconic Supergirl suit until late in the film. Gillespie made this decision deliberately — the costume represents Kara's acceptance of her heroic identity, so wearing it too early would undercut the entire emotional arc of the story. It's a decision that makes complete thematic sense, even if impatient action fans may find the early acts slow.

The film was shot primarily at Warner Bros. Studios Leavesden and on location in London and Scotland, with principal photography running from January to May 2025.

What Critics Are Saying: A Mixed Reception :

The critical conversation around Supergirl has been decidedly divided — with almost universal praise for Alcock, and sharp disagreement about everything else.

At the time of this writing, the film holds a 58% score on Rotten Tomatoes, reflecting that split reception. Here is a snapshot of critical opinion:

Positive takes:

The Guardian (3/5 stars) called it a "sprightly and sparkling superhero yarn" that has "moments when you'll believe this franchise can fly."
Rolling Stone praised the film for going "deep" and proving that niche source material can become genuine mass entertainment without losing its identity.
Empire (3/5 stars) highlighted Alcock's "hungover hero" as delightful, even while noting the film never truly unleashes its potential.

Critical takes:

The Hollywood Reporter called it an "uninspired slog" despite Alcock's committed performance.
Variety was sharp in its criticism, suggesting the film's attempts at a punk-rock aesthetic felt hollow.
Several critics pointed to muddy action sequences, inconsistent tone, and a heavy reliance on musical needle drops as significant drawbacks.

One consistent thread runs through almost every review, positive or negative: Milly Alcock is exceptional. The conversation is not whether she is the right person for this role — she clearly is — but whether the film itself is worthy of her talent.

What Works: The Strengths of Supergirl 2026 :

1. A Genuinely Different Kind of Superhero Story :

The decision to make this a small, personal revenge story rather than a world-ending event is bold and largely correct. Superhero fatigue is real, and a grounded interstellar road movie offers something fresh.

2. Milly Alcock's Career-Defining Performance :

There is simply no overstating how much Alcock elevates the material around her. Every frame she occupies is compelling. She commands the screen with a swagger and emotional depth that immediately establishes Kara as one of the DCU's most interesting figures.

3. The Krypton Flashback Sequences :

The scattered memories of Argo City — Kara's life before the destruction of Krypton — are the film's most emotionally resonant moments. Seeing her trauma through these fragmented recollections rather than front-loaded exposition is smart, affecting storytelling.

4. A Finale That Actually Earns Its Emotion :

Multiple critics who spent most of their reviews picking the film apart admitted that the final act moved them anyway. When Kara finally steps fully into her heroism, the payoff feels genuinely earned.

5. Thematic Ambition :

The film wants to say something real about survivor's guilt, the difference between healing and numbing, and what it means to choose a purpose after catastrophic loss. These are adult themes for a superhero film, and they land more often than not.

What Doesn't Work: The Weaknesses :

1. Inconsistent Tone :

The film cannot decide whether it wants to be a gritty sci-fi western or a quippy Marvel-adjacent adventure. The needle drops — which arrive constantly — often undercut the darker emotional atmosphere the story requires.

2. Muddled Action Sequences :

The close-quarters combat in the first two acts has been widely criticized as sloppily edited, sometimes too dark to follow clearly. For a superhero movie, this is a significant problem.

3. Lobo's Shoehorned Presence :

Jason Momoa is fun as Lobo, but his inclusion clearly serves the broader DCU marketing agenda more than this specific story. His scenes feel like an interruption to the intimate human — or rather, Kryptonian — drama the film is trying to tell.

4. Visual Blandness :

Rob Hardy's cinematography has been called disappointingly flat by several critics. Outside of a handful of genuinely stunning shots, the film looks less distinctive than the source material's gorgeous illustrated pages.

5. The Screenplay's Tonal Inconsistency :

First-time feature screenwriter Ana Nogueira shows clear talent, particularly in the emotional flashback sequences, but struggles to balance blockbuster requirements with the quiet intimacy that makes the comic so powerful.

Box Office Performance & DCU Future :

Supergirl opened on June 26, 2026 following its world premiere at The Plaza at 300 Ashland in Brooklyn on June 22. Thursday night previews brought in $7.8 million, a solid but modest start that reflects the mixed critical reception.

The film carries a reported net budget of approximately $170 million, supported by a $100 million promotional campaign across more than 80 brand partners. Competition from Toy Story 5 on the same weekend has impacted its opening weekend potential.

However — and this is crucial — the box office is almost secondary to Alcock's DCU future. DC Studios co-CEO James Gunn has been explicit about positioning Kara Zor-El as one of the central pillars of the new DC Universe. Alcock is already confirmed to appear with a "major role" in the upcoming Man of Tomorrow (2027), and executive producer Lars P. Winther has described her arc continuing as she reconnects with her cousin and steps more fully into her heroic identity.

In short: Supergirl may not have been a perfect movie, but Milly Alcock's Kara Zor-El is here to stay.

Is Supergirl: Woman of Tomorrow Worth Watching?

Yes — with clear-eyed expectations.

If you go in expecting a glossy, action-packed superhero blockbuster on the scale of Superman (2025), you will likely be disappointed. The film is messier, slower, and tonally uneven.

But if you go in open to a character study about grief and identity wrapped in a space western, with one of the most compelling superhero performances in recent memory at its center, you will find real value here.

Casual fans — worth a theater visit if you're invested in the DCU.
Comic fans — temper expectations about fidelity to the source material; enjoy the emotional core.
Milly Alcock fans — see it immediately. This performance needs to be seen.

FAQ: Supergirl Woman of Tomorrow 2026 :

Q1: Is Supergirl: Woman of Tomorrow connected to Superman (2025)?

Yes. Supergirl is the second film in James Gunn's DC Universe, directly following Superman (2025). Milly Alcock briefly appeared as Kara in Superman before leading her own film. David Corenswet also appears here as Clark Kent / Superman.

Q2: Do I need to watch Superman (2025) before Supergirl?

It helps but is not strictly required. The film functions as a standalone story, though some character context from Superman (2025) enriches Kara's journey and her relationship with her cousin.

Q3: Is Jason Momoa playing Aquaman or Lobo?

Lobo. Momoa transitions from playing Aquaman in the old DCEU to portraying the space mercenary Lobo in the new DCU. His role in this film is supporting rather than central.

Q4: Is Supergirl 2026 based on a comic book?

Yes. It adapts the critically acclaimed 2021–22 miniseries Supergirl: Woman of Tomorrow by Tom King and Bilquis Evely, though the film makes notable changes from the source material.

Q5: What is the Rotten Tomatoes score for Supergirl 2026?

At the time of publication, the film holds approximately 58% on Rotten Tomatoes from critics, with audience scores tracking somewhat higher, particularly in praise of Milly Alcock's lead performance.

Q6: Will there be a Supergirl sequel?

No official sequel has been announced, but Alcock is confirmed for Man of Tomorrow (2027) in a significant role, signaling that Kara Zor-El is a long-term DCU character regardless of this film's box office performance.

Q7: Who directed Supergirl: Woman of Tomorrow?

Craig Gillespie (I, Tonya, Cruella) directed the film. The screenplay was written by Ana Nogueira, with the film produced by James Gunn and Peter Safran of DC Studios.

Q8: What rating is Supergirl 2026?

The film is rated PG-13 and runs approximately 108 minutes (1 hour and 47 minutes).

Final Verdict :

Supergirl: Woman of Tomorrow (2026) is a film of extraordinary talent working against genuine creative friction. Milly Alcock is a revelation — fierce, wounded, funny, and deeply human in a role that demanded exactly that combination. The thematic ambition, the willingness to tell a small, personal story in a cosmic setting, and the film's refusal to resort to planet-destroying stakes all deserve credit.

But uneven action, tonal inconsistency, and a screenplay that struggles to reconcile blockbuster obligations with intimate character drama prevent it from reaching the heights of its source material or its leading performance.

What Supergirl does accomplish, perhaps most importantly, is this: it makes you want to see more of Kara Zor-El. And in the business of building a cinematic universe, that may be the most essential thing a movie can do.
