Phoebe Dynevor Swaps Corsets for Chaos in Netflix’s ‘Thrash’

Phoebe Dynevor is trading the refined ballrooms of Regency-era England for the treacherous waters of South Carolina. The Bridgerton star leads the cast of Thrash, a high-stakes shark survival thriller set to premiere on Netflix on April 10, 2026.

A Fight for Survival in a Category 5 Storm

Directed and written by Tommy Wirkola and produced by Adam McKay, Thrash follows Lisa, a newly single expectant mother. The plot intensifies when a Category 5 hurricane hits her town, trapping her inside her Mini Cooper. As floodwaters rise, Lisa must fight for her life and the life of her unborn child although contending with ravenous bull sharks.

The film features a robust ensemble cast including Whitney Peak and Djimon Hounsou, alongside Alyla Browne, Stacy Clausen, Costa D’Angelo, Amy Mathews, Elijah Ungvary, Dante Ubaldi, Jon Prasida, Gemma Dart, Akosia Sabet, Sian Luxford, and Sami Afuni.

The Physical Toll of Production

Dynevor has described the role as one of the most uncomfortable experiences of her career. To simulate her pregnancy and survive the freezing water, the actress had to wear multiple layers of gear. Dynevor revealed to The Hollywood Reporter that she wore three wetsuits daily, topped with a maternity dress and trench coat to create the pregnancy belly.

The filming conditions were grueling, requiring the use of a “hot hose” to warm her up between takes in the cold water. Dynevor noted that the process of donning three wetsuits and a prosthetic belly was “virtually impossible.”

From ‘Beneath the Storm’ to ‘Thrash’

The project underwent a significant transition before reaching Netflix. Originally titled Beneath the Storm, the film was initially slated for a 2024 theatrical release in the United States via Sony Pictures before pivoting to Netflix and receiving its new title, Thrash.
