Armed with more imagination than most thrillers, this Australian-UK co-production is an intriguing whodunit centred on two privileged schoolboys with an unhealthy interest in the Knights Templar. Nerve centre of the elliptical tale is a British police interrogation room where 17-year-old Alex Forbes (Eddie Redmayne) has been charged with the murder of Nigel (Tom Sturridge), a fellow student Alex openly despised. Alex appears indifferent to the gravity of his situation during a grilling by police inspector McKenzie (Richard Roxburgh), who has to call in forensic psychologist Sally Rowe (Toni Collette) to secure a confession. As Sally discovers, everything fits into Alex’s belief in Gestalt—the attainment of a unified whole that’s much more important than the sum of its parts. From this intriguing setup, the film darts cleverly between Alex’s present psychiatric evaluation and flashbacks to his relationship with Nigel. All this might come across as absurd if it weren’t for a well-honed screenplay that casts further suspicion in several directions. Richard kuipers, Variety.
