LOCKE… Ivan Locke has a long drive ahead of him. He is rushing to London when he should be on site for a massive concrete pour at 5.30 in the morning. The issue is, he’s about to become a father. The problem is, the mother isn’t his wife. His boss is going crazy and there are last minute hitches with the project. Ivan, a meticulous project manager, is trying to keep it all together and do the right thing by everyone, especially the kid who he’s determined will not be born fatherless, like he was.

Audaciously and interestingly, this whole film is set inside Locke’s car. It’s just you and Ivan and a world of voices over his car phone. It’s low-budget, raw film-making by writer-director Stephen Knight which after four days of rehearsals, was shot over just eight days.

It relies heavily on Tom Hardy as Ivan. His calm charm and Welsh lilt make him very likeable even as his life crumbles around him, although it will be interesting to see if women feel the same about him. He’s quite watchable and Tom hardy pulls it off – it’s great acting. And the voices are from a range of top British actors – Ruth Wilson, Olivia Coleman, Andrew Scott – who called Hardy from a hotel as he drove to capture his real reactions.

It feels like a play, and was apparently shot like one, with actors pushing through stumbles and changing their delivery without warning. It’s well shot considering the limitations it places on itself, and you can say that about the whole film… acting, direction, voices of the others are all great, but setting it all in a car and over the phone in virtual real time is a hell of a hurdle. Buckle up – it pulls over at a timely 84 minutes and I never felt like yelling ‘Are we there yet!’ because you know it’s all about the journey. Four gear changes.
