Taut and compactly-sized, Steven Knight’s Locke starring a never better Tom Hardy as a man whose life begins to unravel during a particularly stress-laden drive on a British highway.  The eighty-five minute morality play – a one man show, nearly real-time affair – sounds on the outset like a stage-driven chamber piece that may outstay its welcome a few miles in.  Certainly the idea of  someone yammering on his Bluetooth doesn’t seem to lend itself to entertaining or particularly interesting drama.  Yet, thanks to inventive filming and a commanding lead turn, Locke is an invigorating and alert piece of filmmaking, one where the contrivances are certainly there and made aware, but quickly forgotten due to its human connection to real world stress and anxiety– which to be fair, quite often takes place independently and behind the wheel of a car.
