‘Thrash’ review: Tommy Wirkola’s shark movie ate

Like unsung Australian horror movie Bait, Netflix’s Thrash knows that tsunamis are least of your worries after a Category 5 hurricane hits in a movie. Sharks (yes, sharks) wash in with the tide in the latest from writer/director Tommy Wirkola (Violent Night, Dead Snow), and it’s a proper nail-biter.

With nightmare-inspiring cinematography, increasingly flooded and crumbling sets, impossibly risky scenarios, and solid performances from Djimon Hounsou, Whitney Peak, and Phoebe Dynevor, Thrash earns its place in the long, storied history of shark survival movies.

Climate disaster films come in all genres, and in Thrash (notably produced by Don’t Look Up‘s Adam McKay), Wirkola leans into the extreme weather impact of a warming planet without addressing it directly. Climate change doesn’t cause extreme weather events; climate change increases the intensity, frequency, and duration of extreme weather events. And nothing’s more extreme than watching a Category 5 hurricane absolutely pummel the town of Annieville, South Carolina, with fierce winds, destructive flooding, and sharks swimming down Main Street. (I’m not here to evaluate the scientific accuracy of this film.)

Here, we meet several citizens left behind: Whitney Peak as Dakota, who turns off weather reports to watch videos of her recently passed mother; Phoebe Dynevor as Lisa, a meatpacking factory executive who could give birth any moment now; and Stacy Clausen, Alyla Browne, and Dante Ubaldi as Hanson the Olsens, a trio of siblings whose crooked foster parents see the storm as “just a little bit of weather.” Elsewhere, Djimon Hounsou‘s en route as oceanic researcher Dale, who spotted bull sharks coming in with the storm, seeking shelter in freshwater estuaries. He also happens to be Dakota’s uncle.

We love the Olsens.

You’ll genuinely cheer for these characters as they find themselves suddenly huddled on their kitchen benches, perched on their roof, and on the brink of labor as the floodwaters rise. It’s not an easy feat to craft characters you don’t want to see as shark bait in a movie like this, and Thrash‘s cast manage it with finesse, despite Wirkola giving us very little information about them. Peak’s physicality doesn’t miss a beat, combining Ninja Warrior obstacle courses with convincing anxiety symptoms, Hounsou’s overt authority grants the film legitimacy, and as for Dynevor, well, labor scenes don’t happen like this every day. (And yes, I feel the soundtrack in Lisa’s scenes is internet bait, but I’m not mad about it.)

Thrash is a brutal flood of visual effects and jaw-dropping cinematography.

Although Thrash is a high-budget Netflix film, the nail-biting scenarios Wirkola throws down are simple; often, it’s getting from A to B across shark-infested waters. Like fellow contained shark horrors The Reef, Open Water, The Shallows, and more recently Under Paris, Thrash pushes its characters into survival situations where simply travelling across a tiny stretch of water seems unthinkable. Here, Wirkola stays far from the supershark territory of The Meg or Deep Blue Sea, keeping his marine predators life-size and emphasizing their more terrifying behaviours. However, he does stick to certain shark movie requirements, like characters being suddenly vertically dragged underwater and shark vision camera angles.

Production designer David Ingram builds an increasingly flooded and destroyed town, an impressive and sadly all-too-real vision of disaster — and one which makes for stressful action sequences. Director of photography Matthew Weston’s shots consistently resemble horror movie posters, from a teen teetering over a kitchen doorway as a shark sails underneath to a rooftop SOS with sharks circling below. Each overhead moment plays with shadow, scale, and suspense to up the danger, before editor Martin Stoltz takes us back into the action. And as for action, Thrash throws every last visual effect at sequences like the shocking storm surge, which decimates the entire town of Annieville within minutes.

Make no mistake, Thrash is brutal. The bull sharks, in particular, make for vicious villains, with the species’ signature aggressive tendencies displayed with gruesome work from visual effects supervisor Bryan Jones and his team. (At the risk of sounding like bull sharks’ publicist, bull shark attacks are extremely rare).

If you like shark movies, Thrash is a solid survival thriller with a talented cast and visuals that had me locked in. Wirkola’s ability to balance horror, action, and comedy remains a praise-worthy feat. Dive into it.

Thrash premieres on Netflix April 10.
