There’s little irrefutable about The Irrefutable Truth About Demons, other than the fact that it’s a mess. Directed by Glenn Standring, this early-2000s New Zealand horror feature tries desperately to punch above its weight with feverish style and occult overdrive—but collapses under the weight of its own incoherence.

The film stars a young Karl Urban as Dr. Harry Ballard, a lecturer who stumbles into a demonic conspiracy involving cults, hallucinatory breakdowns, and a lot of unintelligible shouting in dimly lit warehouses. Urban, already showing glimmers of the talent he’d bring to far better roles down the track (The Boys, Dredd, LOTR), does his best to hold the centre—but it often feels like he’s battling the script as much as the demons.

Visually, the film is drenched in grime and erratic camera work, clearly aping the stylistic chaos of late-‘90s horror like Jacob’s Ladder and Event Horizon, but without the clarity or craftsmanship. What could have been an atmospheric descent into paranoia and possession is instead a barrage of half-baked ideas and shrieking performances. The narrative never quite decides if it wants to be a psychological thriller, an urban fantasy, or a cult horror flick—and ends up being none of the above convincingly.

The supporting characters, including a mysterious ex-cultist love interest, offer little substance, and the dialogue ranges from awkward to unintentionally hilarious. The demons themselves—both metaphorical and literal—are reduced to generic growling and bargain-bin effects, robbing the film of any true menace.

The Prognosis:

At the time, The Irrefutable Truth About Demons may have aimed for edgy, underground horror, but in hindsight, it feels more like an overwrought student film with delusions of grandeur. It wants to scorch the screen with dark revelations but instead fizzles out long before it finds its footing.

Thankfully, Karl Urban emerged from this chaos largely unscathed—and the only real truth here is that his career went in a much better direction.
