Netflix’s Thrash: Cast Battles Freezing Temperatures, Sharks For Survival Thriller

by

The actors in Netflix’s new shark horror movie didn’t just pretend to battle tough conditions – they genuinely did. Filming was incredibly challenging, with freezing water, strong winds, and even a surprising use of lubricant on set, pushing the cast to their physical limits in ways viewers won’t realize.

This intense thriller follows a town devastated by a massive hurricane. As floodwaters rise, trapping residents, a new terror emerges: sharks are swept in with the storm, turning a disaster into a desperate battle for survival against both the elements and the predators now lurking in the flooded streets.

In a recent interview with ScreenRant, stars Phoebe Dynevor, Whitney Peak, and Djimon Honsou discussed the challenging experience of filming their shark horror movie. They playfully admitted to enduring difficult conditions for the sake of the film, with Dynevor teasing that Honsou had it easiest. Both she and Peak acknowledged that the cold water they filmed in could have been even more unpleasant.

Phoebe Dynevor shared a funny story about how they kept warm on set. To avoid getting dangerously cold from constantly wet hair, the hair and makeup team used a special lubricant to look like their hair was soaking wet, even though it was actually dry. She also thanked the stunt coordinator for providing a heated hose nearby when they filmed scenes in cold water. Between takes, Phoebe and her co-star Whitney would use the hose to warm up inside their wetsuits, giving them about two minutes of relief before the next take.

Whitney Peak recalls having a lot of fun as kids, warming themselves with hot water bottles around their necks.

Honsou arrived by boat, named Trona, to help, and he later confessed to ScreenRant that he felt somewhat bad about being dry and safe while his co-stars, Dynevor and Peak, were soaking wet in the cold water.

Djimon Honsou: I felt for you guys when I showed up with my boat, Trona.

Phoebe Dynevor: When the storm had passed.

Whitney Peak: How convenient. How convenient for you.

Everything Else The Cast Said About Filming The “Insane” Survival Thriller

ScreenRant asked the filmmakers how they managed to balance realism with a sense of fun in their disaster/shark movies, noting that both elements are important for those types of films to work.

Honestly, the enjoyable parts of filming were pretty limited. The artificial rain and strong wind were a little fun, like playing as a kid. But mostly, I felt comfortable focusing on my character’s search for his niece. It was reassuring not to be constantly underwater, because I’m not a strong swimmer and I don’t like feeling out of control in the water. Being in that ocean environment, surrounded by sharks and things, was genuinely unsettling and uncomfortable for me.

Whitney Peak: I think the subject matter, the movie itself, was pretty heavy.

You know, watching the cast and crew on set, it was clear they had a blast. Despite spending what felt like all day soaking wet, everyone kept things light and playful. It really felt like a group of friends just goofing off, which made the whole experience seem so much more enjoyable. It’s that kind of energy that always shines through on screen, and I think it’s a huge part of what makes this project so charming.

Djimon Honsou explained that the cast and crew felt a sense of camaraderie and mutual support while filming underwater scenes, as everyone experienced the challenges together.

When filming, we often used large water tanks, and everyone on the crew wore wetsuits. It created a real sense of teamwork and shared experience.

The person being discussed is going through a really tough time, and it just keeps getting worse. It’s like everything is piling up on her at once, similar to the feeling at the end of the movie The Truman Show. She’s really having a bad day.

Things are really escalating for my character – she’s in labor with increasingly strong contractions, and at the same time, a hurricane is getting worse. It’s a lot to balance, portraying both of those intense experiences at once.

Honestly, watching Whitney Peak talk about acting really resonated with me. She described a scene where a young actor was clearly having a panic attack, and the other performer just felt completely lost – like, ‘What on earth is going on here?’ It’s such a raw and relatable moment, and it perfectly captures the unpredictable energy you get on set.

Phoebe Dynevor: Where’s this going to end up? It only gets more insane as the movie goes on.
