Written and directed by Demián Rugna (Satanic Hispanics; Terrified). Produced by Fernando Díaz and Roxana Ramos. Executive produced by Emily Gotto and Samuel Zimmerman.

Plot:
In a remote village, two brothers discover a demon-infected man just about to give birth to evil itself. In a time when exorcism looks to be of little use to ward off evil, after warning the neighbours in town, they decide to get rid of the man but merely succeed in helping him to deliver the inferno…

TIFF blurb:
“In this shocking supernatural chiller from Argentine master of horror Demián Rugna (Terrified), two brothers race to prevent the spawning of evil incarnate as an epidemic of demonic possessions spreads through their rural community.
Something or, more accurately, someone is rotten in the state of Argentina. In this context “rotten” refers to a kind of demonic infection that consumes its host, transforming them into a vessel for evil incarnate.
When brothers Pedro (Ezequiel Rodríguez) and Jimmy (Demián Salomón) discover that a “rotten” has been festering in a nearby farmhouse — its very proximity poisoning the local livestock — they attempt to evict the victim from their land. Failing to adhere to the proper rites of exorcism, their reckless actions inadvertently trigger an epidemic of possessions across their rural community. Now they must outrun an encroaching evil as it corrupts and mutilates every man, woman, and child it is exposed to, and enlist the aid of a wizened “cleaner,” who holds the only tools that can stop this supernatural plague.
A wildly original take on satanic panic, When Evil Lurks is the latest supernatural shocker from writer-director Demián Rugna, whose last film, Terrified, similarly served up a series of finely tuned scares and grotesque nightmare imagery. Eschewing conventional exposition, Rugna trickles the unique rules and lore that define these viral possessions across the brothers’ struggle to combat the chaos, and soaks the escalating terror with a brutality that recalls the gory extremities of Lucio Fulci’s City of the Living Dead and the hopeless horror of Narciso Ibáñez Serrador’s Who Can Kill a Child?” TIFF
Writer-director Demián Rugna has said:
“When Evil Lurks will be a double challenge for me and the viewer – complex to stage and also very stark for anyone who watches it. I needed to leave the scheme of a contained production to break with everything. This movie will be my relief, a release of disturbing images that have been accumulating in my head over the years like a pressure cooker.”
Co-producer Fernando Díaz commented:
“We’re trying to tell a macabre story with an extremely oppressive and realistic atmosphere, but with a frantic rhythm, without abandoning a strong narrative. A genuine universe that re-signifies the tales of evil and curses; a rural environment on a monotonous plain, interrupted by a series of images and extremely lurid sequences.”
Reviews:
” …a feel-bad midnight movie of the highest order; an escalating series of geographical shock-and-gore horror set-pieces that’s sure to satisfy the type of genre cinephile who will laugh at a brilliantly executed child-rag-doll dummy effect without sacrificing the haunted, miserable, dusty horror paperback atmosphere that it works so hard to instill. There are possessed goats/dogs, ancient fable-like axe murders, and shock vehicle carnage galore…” Blood Knife
“When Evil Lurks operates more on a dread-soaked atmosphere and a commitment to fearlessly bludgeoning, biting, and bone-shattering taboos […] Its themes of infectious evil resonate while its frights deliver maximum impact, even if its story unravels a bit at the seams. It’s this, combined with a refreshing spin that eschews the conventional possession horror formula, that ensures When Evil Lurks continues Rugna’s streak for terrifying audiences.” ★★★½ Bloody Disgusting
“When Evil Lurks is a brutally violent horror film that effectively builds tension and delivers gruesome scares. The film embraces chaos and leaves no character safe, offering a refreshing willingness to really go there compared to other genre movies. While it has some narrative weaknesses, the film’s relentless energy and absurdity make it a compelling and dread-inducing experience.” Rating: B Collider
” …the first half of the picture is a very hard-hitting series of events that range from shocking to gruesome, including build-up to a great jump scare. Then the movie shifts gears, becoming quiet and unsettling but still frightful. Rugna skilfully weaves together a ghastly chain of events that chills audiences with its dreadful subtlety. It generates an eerie atmosphere…” Digital Journal
“What makes this movie so good and unsettling is that it’s true to the title and storyline; it’s just pure evil. It makes you want to look away or cover your ears but even when it’s over the feeling forces you to sit with it a little bit longer. Love the cultural aspects from Argentina that shine through.” ★★★★ Elisa Paszt Ornelas
“A fun premise can get a horror film far, and When Evil Lurks has one that could be taken to interesting, terrifying places. But rather than lean into what makes its world of demonic diseases intriguing, the film squanders its own potential by leaning into its worst qualities and instincts. Instead of giving us something feverishly nightmarish, it ends up running as tepid as a minor head cold.” Grade: C IndieWire
” …an escalating slow-build series of surreal, tangible, geographical shock-and-gore horror set-pieces that’s sure to satisfy the type of genre cinephile who will laugh at a brilliantly executed child-rag-doll dummy effect or some goopy brain-eating without sacrificing the haunted, miserable, dusty horror paperback atmosphere that it works so hard to instill…” ★★★★ Josh Lewis
“In the end, there’s enough unforgettable imagery in When Evil Lurks to overcome its unfulfilled potential. The right audience will eat it up, ignoring both the undercooked and overcooked ingredients in this bloody stew, if they’re not too nauseous to do so.” ★★½ RogerEbert.com
“Everything is done in camera and Rugna once again enlisted the skills of his effects artist from Terrified, Marcos Berta, to bring amazing gore to the screen. Combined with some sick production (creature) design from Laura Aguerrebehere horror fans are going to be very happy. There are set pieces in this film that will haunt us for the rest of our days.” Screen Anarchy
“When Evil Lurks is a perfect Midnight Madness movie. It’s dark, twisted, and full of jump scares and gnarly visuals. Like the best horror flicks, it delivers a cerebral commentary on real-world issues. Rugna once again delivers a shocking and sinister descent into depravity guaranteed to shake viewers to their core. ” That Shelf
“While When Evil Lurks doesn’t have the sheer amount of mayhem that some other recent films have, Rugna stages some scenes that you won’t soon forget […] When Evil Lurks isn’t on the same level as Terrified, but that is a high bar to set. It is a disturbing, bloody, and frightening film that manages to be thought-provoking at times. Rugna has delivered an excellent film…” ★★★★ Voices from the Balcony
“There are a few really hideous images in this one, which is great.” ★★★ Will Sloan
