Phoebe Dynevor Battles Sharks in ‘Thrash’ and Teases New Shyamalan Mystery Film

Phoebe Dynevor spent long days submerged to film Thrash. She plays Lisa, a nine-months-pregnant woman trapped in a Mini Cooper during a Category 5 hurricane.

On-set ordeal and physical demands

The story places Lisa in a flooded South Carolina town surrounded by bull sharks. The production staged her confinement inside a small car as waters rose around it.

Filming took place in Melbourne, Australia, during winter. Dynevor said the cold water and layered costuming made the shoot exceptionally uncomfortable.

• She wore three wetsuits on many days.
• She also donned a pregnancy prosthetic, a maternity dress and a trench coat.
• Between takes, a hot hose warmed her inside the suits.

Behind the scenes and production notes

Netflix acquired Thrash from Sony and released it on April 10. The film was produced by Adam McKay and directed by Tommy Wirkola.

The project went through several titles, including The Rising, Beneath the Storm and Shiver. The final title, Thrash, highlights the movie’s violent storm and shark elements.

Dynevor described a moment of claustrophobia on set. She also recounted a panic episode while filming inside the cramped Mini Cooper.

Character and thematic research

Lisa is abandoned by her fiancé and must fight for her and her baby’s survival. Dynevor researched childbirth and spoke with women who delivered in unconventional conditions.

The film mixes thriller elements with commentary on climate extremes. Dynevor praised McKay’s awareness of environmental impact in the story.

Shyamalan collaboration and Remain

Dynevor also discussed her role in Remain, the M. Night Shyamalan film she describes as a blend of romance and horror. The story was co-conceived by Shyamalan and novelist Nicholas Sparks.

The Sparks novelization was published in October 2025. Dynevor was not allowed to read the book before shooting, she said, because the film and novel differ.

Remain moved its theatrical release from October 2026 to February 2027. Dynevor plays Wren opposite Jake Gyllenhaal, who portrays a grieving architect named Tate Donovan.

On set with Shyamalan and Gyllenhaal

Dynevor called working with Shyamalan and Gyllenhaal a learning experience. She said their collaboration brought both romance and unexpected twists to the film.

Career context and other projects
