Kaia Gerber and Amy Landecker co-star in Max Minghella’s second film, premiering at the Toronto Film Festival.

Shell is a film made with the intention of being a guilty pleasure. It wants to be the film one would encounter on cable in the middle of the day or late at night. Many films have become popular this way, especially before the days of streaming: scrappy little films with a campy sense of humor and talented cast getting to play around and stretch their acting muscles in ways that feel low-stakes for their career. Worst case scenario, the film becomes a curiosity — not good, but fascinating enough in its badness. And the best-case scenario is becoming one of those hidden gems that have a second life on home video.

Enter Zoe Shannon (Kate Hudson) and her beauty empire — her company Shell has created a new kind of treatment that is meant to improve the body’s overall health and halt the aging process. Samantha is hesitant at first, but she’s quickly convinced by the handsome Dr. Hubert (Arian Moayed). At the clinic, she runs into a young woman she used to babysit, Chloe Benson (Kaia Gerber), and the two reconnect. Still, Samantha wonders why someone so young would even need the treatment. Chloe is brand new to acting, but she’s already competing with Samantha for roles. Why would she need to make any changes now, so early in her career?

Samantha blossoms, getting the film role of her dreams and feeling sexy for the first time in her life. But when the treatment starts to give Samantha unforeseen side effects, the facade of Zoe and her beauty empire starts to crack. Soon, Samantha realizes that whatever happened to Chloe is happening to her too. 

Somehow, at 100 minutes, Shell still feels too short. Writer Jack Stanley’s script zips through scene after scene, without much room to pause and ponder where the story is going. Moss does her best as Samantha, but the character is so thinly written there’s not much to hold onto. Samantha’s transformation is largely an internal one, where she gains her confidence and all her problems seem to fall away.

The story comes into sharper focus as the horror elements slowly creep in. The body horror aspects are among the most interesting, injecting the film with a nice dose of violence. Hudson is having a lot of fun as Zoe, but the film keeps stopping short of making her a full-on camp villain. Everything she does feels a little too tame, too neat, when she should be getting her hands dirty. Shell is at its best when it goes for the grotesque, but the look of the film is a little too clean to fully sell it. The visceral nature of classic camp horror is what makes it so memorable. There’s bravery in a film that’s not afraid to commit to being ugly.
