Radius (2017) is a compelling Canadian-Belgian sci-fi thriller that masterfully blends mystery, horror, and psychological drama. The film follows Liam, who awakens from a car accident with complete amnesia, only to discover a terrifying ability: anyone who comes within a 50-foot radius of him dies instantly. This chilling premise sets the stage for a tense narrative where Liam must navigate his isolation while trying to uncover his past.

Director Caroline Labrèche and Steeve Léonard create a haunting atmosphere that emphasizes psychological tension over cheap scares. The film's strength lies in its clever plot twists and the evolving dynamic between Liam and Jane, a woman who appears immune to his deadly radius. Their relationship becomes the emotional core of the story as they piece together fragments of memory that might explain the phenomenon.

Diego Klattenhoff delivers a nuanced performance as Liam, effectively portraying the character's confusion, fear, and moral dilemma. Charlotte Sullivan equally shines as Jane, adding depth to what could have been a straightforward thriller. The cinematography captures the bleak Canadian landscape, mirroring Liam's internal isolation.

Viewers should watch Radius for its intelligent take on the sci-fi thriller genre, offering more cerebral suspense than typical horror fare. The film raises thought-provoking questions about identity, consequence, and human connection while maintaining steady tension throughout its 93-minute runtime. With its original concept and strong execution, Radius provides a satisfying viewing experience for fans of psychological sci-fi and mystery thrillers.
