A guy in a BMW. Alone. Talking on the wireless. Voices on the speaker. He’s Ivan Locke, a Brit, driving from Birmingham to London. In real time – 85 minutes. No flashbacks. Just this guy. Juggling crises. Don’t freak out. Locke only sounds like a trap. It’s a powerhouse of claustrophobic suspense and fierce emotion, mostly because Tom Hardy, best known as Bane in The Dark Knight Rises, is a blazing wonder as Locke. Writer-director Steven Knight has given Hardy the task of holding us spellbound as Locke, a husband and father, drives away from his biggest job ever as a construction manager and into the arms of a one-night stand who’s about to have their baby. The voices of boss (Ben Daniels), crew chief (Andrew Scott), lover (Olivia Colman), wife (Ruth Wilson) and sons (Tom Holland, Bill Milner) jangle in Locke’s head, and ours, as he makes his life-changing journey. Hang on.
