Nightborn movie arrives in UK cinemas and on Shudder on 30 October 2026, just in time for Halloween weekend, and it is not a comfortable watch. It is a Finnish folk horror about new parenthood, a decaying house in the forest, and a baby who does not look or behave quite the way a baby should. Rupert Grint, best known to millions as Ron Weasley, plays a husband who slowly realises that his wife’s fears may not be paranoia at all.

A baby called Kuura, and a suspicion no one wants to say aloud
At the centre of Nightborn movie is Saga, played by Seidi Haarla, and her British husband Jon, played by Rupert Grint. The couple leave the UK and move into the isolated Finnish forest home where Saga spent much of her childhood, a house once owned by her grandmother. They hope the quiet, the trees and the fresh air will be the perfect place to start a family.
Their baby arrives, and they name him Kuura, the Finnish word for frost. But Kuura is covered in hair, and Saga begins to suspect that something about her child is not entirely human. The film never hands the audience a simple answer. Instead, Nightborn movie keeps two explanations alive at once: that a supernatural force from the forest has touched this family, or that exhaustion, isolation and the strain of first-time parenthood are twisting what Saga sees. That ambiguity is the film’s most unsettling trick, because the viewer, like Jon, is never quite sure whom to believe.
As the suspicion grows, the marriage itself starts to fracture. Saga carries her fear alone, Jon grows frustrated and frightened in a different way, and the house, with a tree growing through its front room in one memorable image, seems to close in around them. Nightborn movie is therefore as much a drama about a couple falling apart as it is a horror film, and that is why its scares land harder than a string of jump scares would.
Troll folklore from the Finnish forest
Nightborn movie draws on Finnish forest folklore, and in particular on old stories about trolls and changelings, the eerie idea that a child might be swapped for something else. Director Hanna Bergholm does not explain the folklore in a lecture. She lets it seep through the setting: the deep forest, the remote house, the whispers of local belief, and the sense that nature here is not a pretty backdrop but a living, watching presence.
That folk-horror roots give Nightborn movie a different flavour from a standard haunted-house film. The horror is slow, damp and earthy, tied to pregnancy, birth and the body itself. Critics have described it as maternal horror and body horror, and both labels fit. The film asks what happens when the most natural thing in the world, having a child, starts to feel unnatural, and it refuses to look away from that question.
The cast: Seidi Haarla leads, Rupert Grint surprises
Seidi Haarla carries Nightborn movie as Saga. Haarla won acclaim for Compartment No. 6, and here she gives a performance that reviewers single out again and again: fierce, exhausted, funny in flashes, and utterly convincing as a new mother who is both fiercely protective and quietly terrified of her own child. If the film works, it works because Haarla makes Saga’s fear feel real even when the audience cannot decide whether it is justified.
Rupert Grint is equally important as Jon, and this is a very different role from his Harry Potter years. Jon is an outsider in Finland, a British husband trying to be supportive while watching his wife slip away from him. Grint plays him with a tired, ordinary warmth that makes the horror feel closer to home. When Jon finally confronts what may be happening, it hurts precisely because he has tried so hard to be reasonable.
The supporting cast adds to the film’s strange, closed-in world. Pamela Tola plays Taru, Pirkko Saisio plays Saga’s mother, and Rebecca Lacey and John Thomson play Jon’s parents. None of them offers Saga an easy rescue. Instead, each one adds another layer of doubt, family history and local knowledge, which is exactly how folk horror should work.
Hanna Bergholm, from Hatching to Nightborn movie
Nightborn movie is the second feature from Finnish director Hanna Bergholm, who co-wrote it with Ilja Rautsi. Her debut, Hatching, premiered at Sundance in 2022 and built a cult following for its mix of coming-of-age drama and grotesque body horror. Nightborn movie continues that path, but with an adult subject: parenthood rather than adolescence.
Bergholm’s films share a fascination with the body changing in ways that cannot be controlled, and with families that look normal from the outside while something rotten grows inside. In Nightborn movie, that fascination is at its most personal. The hair-covered baby Kuura is brought to life with realistic puppets and unsettling sound work, rather than glossy digital effects, which is why close-ups of him feel so queasy. Bergholm wants the audience to feel the same queasy uncertainty as Saga: is this a monster, a miracle, or a mother’s worst fear made flesh?
The film premiered in competition at the Berlin International Film Festival in 2026, played the BFI London Film Festival, and won the Cheval Noir trophy for best film at the Fantasia International Film Festival. That festival journey matters, because it shows Nightborn movie was not made as a throwaway Halloween title. It was made to be argued about.
What the reviews say: striking, powerful, and not for everyone
Reviews of Nightborn movie are mixed in an interesting way, and honest viewers should know both sides before buying a ticket. On the positive side, critics praise its striking visuals, its powerful central performance from Seidi Haarla, and its willingness to go somewhere genuinely disturbing about motherhood. One reviewer called it gloriously grisly folk horror, while another said it gave them the same disturbing feeling as last year’s Bring Her Back.
On the other side, some critics found the film overstuffed, arguing that its Finnish myths get lost in a thicket of ideas and that its scares, while striking, sometimes feel familiar. The BFI’s Sight and Sound review made exactly that point, calling it a gory post-partum horror whose folklore does not always cohere. That split is useful to know: Nightborn movie is bold and original, but it is not a tidy, crowd-pleasing horror film. Viewers who like slow, atmospheric folk horror will get far more from it than viewers who want a fast, jump-scare ride.
For Halloween weekend, that makes Nightborn movie a strong alternative to the bigger, louder releases. It is the kind of film people argue about afterwards, which is often the sign of a horror film worth seeing.
Where to watch Nightborn movie, and what is next
Nightborn movie is released in Picturehouse cinemas and on Shudder in the UK on 30 October 2026, according to Love Horror’s release report, with a runtime of around 92 minutes. It is also arriving on Blu-ray and DVD in December 2026, with a digital release to follow, so viewers who miss it in cinemas will have another chance before Christmas. No separate Indian theatrical date has been confirmed at the time of writing, so Indian viewers should check Shudder availability in their region.
Like other UK releases this weekend, including I Love Boosters movie, Nightborn movie shows how crowded and varied the Halloween cinema slate is this year, from fashion capers to folk horror. Nightborn movie is the darkest choice of the bunch, and for horror fans, that is precisely the point.
