It's becoming increasingly common to transform well-known fairy tales into horror films, tapping into the nostalgia of childhood favorites. The Norwegian film The Ugly Stepsister stands out in this trend, offering a profound commentary on its source material, Cinderella. Unlike other adaptations that might lean heavily into shock value, this movie delves into meaningful themes, blending body horror with a critique on beauty standards.
The film has made quite an impact, with Variety reporting a viewer vomiting during its Sundance premiere, highlighting its intense nature. It boasts an impressive 95% score on Rotten Tomatoes, with IGN's critic Katie Rife noting, "A strong stomach is non-negotiable... as The Ugly Stepsister takes the concept of suffering for beauty to graphic, nauseating extremes."
If you're curious to test your own resilience, The Ugly Stepsister is now available for home viewing.

You can stream The Ugly Stepsister on Shudder, a horror-centric streaming service that offers a 7-day free trial and starts at $7.50 per month. Shudder is also included in AMC+ memberships. Alternatively, if you prefer not to commit to another subscription, the film is available to rent or buy on platforms like Prime Video.
The movie's transition to streaming platforms comes shortly after its U.S. theatrical release, which followed nearly five months after its debut at the 2025 Sundance Film Festival. It also premiered in Norway a month before hitting North American screens, indicating a solid theatrical run for an independent horror film.
The Ugly Stepsister (Den stygge stesøsteren in Norwegian) draws its inspiration from the Brothers Grimm version of Cinderella, rather than the Disney adaptation. According to IGN, "The Ugly Stepsister depicts crude and agonizing cosmetic-surgery procedures that – believe it or not – are not that far off from historical reality." This mix of body horror and a critique on beauty standards echoes themes found in last year's The Substance. Here is the official synopsis:
Determined to outshine her beautiful stepsister, Elvira resorts to extreme measures to win the prince's heart in this dark re-imagining of the Cinderella fairy tale.

The Ugly Stepsister marks the feature film debut of writer-director Emilie Blichfeldt. The cast includes:
