Harmful Animals has a killer hook: Jai Courtney stars as a deranged serial killer who makes use of sharks as his weapon of selection.
It sounds bonkers, like one thing you’d see in an previous Batman comedian, in an Austin Powers film, or on late-night TV, again when the adverts have been all 1-900 numbers. However props to screenwriter Nick Lepard and director Sean Byrne. They carry blood and chew to this funky premise, delivering a film that is deep in dread, sweat, thrills, and chills.
Positive, when sharks swim into horror, issues can get fairly gnarly. The all-time basic is Jaws, the place the gore of chewed-up human stays is balanced with an interesting character-driven drama. Splashier slaughters got here from that seminal movie’s extra vicious offspring, starting from the shark slasher Deep Blue Sea to extra practical thrillers like The Shallows and 47 Meters Down, with the over-the-top Jason Statham journey The Meg and the proudly trashy Sharknado movie sequence taking a extra gonzo method to the subgenre.
But, Harmful Animals is not of this breed. As an alternative, sharks on this film are type of a bait and swap for one thing extra stunning and much more sinister.

These conversant in Sean Byrne’s earlier movies is probably not stunned to find the sharks aren’t the scariest issues in Harmful Animals. No shade to those kings of the ocean. Cinematographer Shelley Farthing-Dawe and editor Kasra Rassoulzadegan masterfully seize and edit photographs of sharks swimming with a scrumptious sense of menace. Some such scenes are so hanging in the way in which they painting the ability and measurement of those creatures that it actually took my breath away. However sharks will not be the monsters on this film. They’re simply being sharks!
The monster right here is Tucker (Courtney), a sun-cooked Aussie who makes a residing on the Gold Coast by taking vacationers out on his boat to go on shark dives. Positive, many come and go together with nothing however a brush with nature and completely satisfied recollections. However from the movie’s horrifying opening sequence, audiences are made conscious of Tucker’s darkish facet. It is not simply chum this rugged fellow tosses overboard to the sharks. He feeds them ritualistically, feeling a deep connection to the beasts and taking particular pleasure in watching them feast — on younger girls particularly.
That is according to Byrne’s model of horror, which tends to heart the horrible issues mankind does to its personal. The Aussie filmmaker made his debut with 2009’s The Cherished Ones, which centered on a teen lady taking out her most twisted needs on a kidnapped crush. Then in 2015 got here The Satan’s Sweet, starring Ethan Embry as a household man (and metalhead) who strives to guard his teen daughter from the homicidal urges of a mentally unwell (or arguably possessed) previous man.
Harmful Animals feels a pure development for Byrne, containing the heavy-metal vitality of his sophomore movie with the sadistic glee of his first. And Courtney proves his pitch-perfect collaborator in making a film that is unrelentingly twisted and rousingly entertaining.

(See the man versus bear debate of 2024.)
Remarkably, as thematically darkish as Harmful Animals is, watching it’s electrifying and wickedly enjoyable. Whether or not small-talking with a scruffy native, rigging up a sufferer for feeding time, or dancing round ritualistically to rock music in pink underwear, Courtney is a reside wire, sparking so intensely that his villain appears able to something.
Cheers to Harrison who matches his vitality with a strong disgust as Zephyr. Collectively, they construct a cat-and-mouse story that’s jolting, in the way in which of Byrne’s earlier movies.
