WΔZ

WΔZ (2007) is a British crime horror you can watch online on iFILM, directed by Tom Shankland. The title refers to the Price equation — a formula from evolutionary biology that models when an organism will sacrifice itself for another. Someone in the city is carving it into victims and making the theory literal: kill the person you love most, or be killed yourself.

Detective Eddie Argo (Stellan Skarsgård) and his new partner Helen Westcott (Melissa George) work the case through a series of crime scenes that keep getting harder to read. Selma Blair plays a figure whose history eventually explains where the killer's logic comes from. Tom Hardy has a small but sharp early appearance. The film doesn't rush to its answers — it's more interested in the equation than in the gore.

Shankland pitches it closer to cold procedural than to splatter, which makes the horror land differently than expected. Stream WΔZ (2007) online on iFILM — a dark British thriller built on a genuinely unsettling philosophical premise.
