Locke: minimalist experience that it is, Steven Knight’s film is also a very engaging one, thanks to the strong acting of Tom Hardy. It is a simple, no-frills human drama, easy to relate to. Given the single (of sorts) location, Justine Wright’s editing make great use of Haris Zambarloukos’s varied images. However, there’s no denying that Hardy is the main reason to see this; he has limited instruments to use (his voice’s modulations, his posture and his eyes, mostly) but even so gives a nuanced, rich performance.
