- Quick Answer: From campy 80s cinema to the Arrowverse and the modern DCU, Supergirl's on-screen legacy spans four major live-action eras essential for any fan.
With the new DCU movie Supergirl on the horizon, there’s never been a better time to dive into the Girl of Steel’s onscreen legacy.
Since her comic debut in 1959, Kara Zor-El has been one of DC’s most powerful and enduring icons. Over the decades, she’s been reimagined across animation, live-action TV, and film, with each era bringing something entirely different to her character.
Before she takes flight in her new solo DCU adventure, here is your short guide to Supergirl's most essential movies and TV shows from the past.
Supergirl (1984)
Supergirl made her big-screen debut in 1984, with then-newcomer Helen Slater stepping into the boots of the titular hero. Unfortunately, the film carries a notorious reputation for clunky storytelling and a campy tone that couldn't match the magic of the early Christopher Reeve Superman films.
However, it's still a fascinating watch today. Slater herself delivers an incredibly charming, earnest performance, and seeing her take flight offers a distinct look at early superhero filmmaking. For DC fans, it’s a vital piece of cinematic history that highlights exactly how much the future live-action adaptations have evolved since.
Smallville
In the later seasons of Smallville, Kara Zor-El flew into the mix and immediately became a major standout for viewers, thanks to Laura Vandervoort's charismatic performance. Her arrival brought a fresh dynamic to the series, offering a fascinating look at how she and Clark bonded over their shared Kryptonian heritage.
While her character didn't stick around as a permanent fixture in the show's ten-year run, her arc was pivotal. At a time when Supergirl still hadn't fully crossed over into mainstream pop culture, Smallville successfully reintroduced her to a massive weekly television audience, paving the way for her own headlining series years later.
Supergirl TV Series (2015-2021)
Decades later, Kara Zor-El finally got the live-action spotlight she deserved with her own self-titled series in The CW’s Arrowverse franchise. Spanning six seasons, Melissa Benoist stepped into the cape, delivering a defining performance that successfully reintroduced the Girl of Steel to a whole new generation of mainstream viewers.
The series became a massive hit with fans by completely embracing its comic book roots, weaving in iconic DC lore, and tackling poignant, real-world themes. For many, Benoist's optimistic portrayal became the gold standard, proving that Supergirl could effortlessly stand on her own and not just be seen as Superman's cousin.
The Flash (2023)
Supergirl officially entered the DCEU in The Flash, with Sasha Calle stepping into the role for a striking, multiversal twist. Though she played a supporting part, Calle’s Kara Zor-El was a major highlight of the film, delivering a fiercer, more grounded, and distinctly edgy interpretation of the hero that set her apart from previous versions.
Unfortunately, this marked Calle's only time in the cape. The subsequent DC franchise reboot quietly canceled plans for her own solo spin-off project. Despite her brief tenure, she remains widely regarded as one of the absolute strongest and most memorable elements of an otherwise deeply flawed movie.
Superman (2025)
Milly Alcock's Kara Zor-El officially made her highly anticipated DCU debut during the final moments of last year's Superman. It served as a thrilling first look for fans, offering a brief but telling glimpse into how this new universe will interpret the iconic hero ahead of her own standalone film.
While her screen time was intentionally brief, the movie is a mandatory inclusion on this list. Beyond the massive implications for the DCU's interconnected future, it gave audiences their first taste of Supergirl alongside her companion Krypto, perfectly setting the tone for the cosmic adventure waiting just around the corner.
