Harbinger is a 2026 English supernatural slasher horror film written by Harry Boxley and Simon Cluett and directed by James Crow. Cutting his teeth as a writer/director in 2010 with the shorts Playtime and Cold Turkey, James continued to create a slew of short films from 2012 to 2014 until his first feature-length film, Curse of the Witching Tree (2015). Afterwards, he would proceed to write and direct numerous independent films of differing genres, such as House of Salem (2016), Black Creek (2017), and A Suburban Fairytale (2021).
Julia, the sole survivor of the late serial killer, Henry Decker, is lured back to the house she shared with him for a ghost-hunting TV show. The crew discover the ‘Harbinger’—a fairground fortune-telling machine that reveals their fates one by one.

Offering a playful mix of Ghost Hunters and supernatural elements from Tom Holland’s Child’s Play, Harbinger often struggles with its own identity. While the narrative and dialogue are often tongue-in-cheek and darkly comedic, the film’s overall tone is presented too seriously to fully embrace this campy overtone. Yet this sober, weighty atmosphere is severely undercut by the jocular nature, conversely detracting from both aspects. Additionally, the film suffers from pacing issues at points. At only 88 minutes, the long stretches of characters navigating the paper-thin plot can cause the tempo to drag—especially in the final act.
Despite this, Harbinger does bring some interesting ideas to the table. The titular fortune-teller machine acts as a captivating conduit for the supernatural aspects. Designed to resemble classic fortune-teller machines found in seaside towns throughout the English coastline, it successfully captures their eerie, antiquated aesthetic—complete with creepy animatronics. Furthermore, the cards each character receives from the machine are tied to their later demise are a nice touch, being reminiscent of Freddie Francis’ classic horror Dr. Terror’s House of Horrors (1965).

However, the film’s biggest setback is the lack of implementation of the titular Harbinger character. A mix of campy and imposing, the character design is pretty neat. Though, with his appearance limited to only a handful of times, and only seconds in length, the character is sadly underutilised
Featuring competent visual design, the cinematography in Harbinger is one of its standout aspects. Utilising fantastic shot composition, the framing and camera movement feel purposeful—harking back to the days of classic English horror such as Hammer House of Horror (1980). However, the cinematography isn’t without issues. The included B-roll, though brief, feels out of place because it was filmed on a different camera, seemingly out of opportunity. Furthermore, the sweeping establishing shots filmed via drone, while a great addition, lack the same colour grading as the rest of the film, feeling flat and, again, out of place.

Another of Harbinger’s positives is its implementation of practical effects. While limited in their use throughout the film, the effects still offer a sufficiently gruesome depiction of slasher violence. Yet, instead of offering a glorified smorgasbord of blood and gore, it goes for a more grounded, pragmatic delineation of murder. This less-is-more approach works in the film’s favour, still providing a visceral experience while working within the production’s small budget.
Offering a mixed bag of performances, the acting in Harbinger can range from enthusiastically melodramatic to underwhelming. The antagonist, Henry Decker, played by Peter Woodward, delivers a delightfully facetious, over-the-top performance, chewing the scenery in every scene he appears in. However, the main protagonist, Julia, played by Jeanine Nerissa Sothcott, delivers an adequate performance, though it is a rather tepid display overall.

Suffering from writing problems and littered with pacing issues, Harbinger can be a languid watch at times. While it has an interesting narrative concept, reminiscent cinematography, and decent practical effects, its lack of direction and underuse of the titular antagonist character unfortunately outweigh these positives—providing a mediocre experience overall.

Harbinger is available to digitally through Amazon Video and Apple TV.
