If Idris Elba is the current bookies favourite to be the next Bond, The Sloth is hedging a long range bet on Jack O’Connell being Idris’ successor.  Already a master of Bond’s essential moody, thousand yard stare and no stranger to cinematic violence, squint a bit and he could be Daniel Craig’s little brother.

In ’71 Jack plays young British squaddie Gary Hook.  A newbie recruit, still green around the edges, Gary finds himself dispatched to the Northern Ireland of the early 1970’s – not a good place to be for a British soldier. His regiment are charged with keeping a very fragile peace in an anti-British Belfast, at a time when IRA militant violence was at its peak. Commanded by a naively inexperienced officer who believes a cheerful smile will get the locals on-side, his regiment are sent to patrol the unpredictable streets with minimal defensive kit.

Within minutes, things take a turn for the worse.  A mob of aggressive locals surround the young soldiers, taunting and baying for blood. Tension and panic mounts and the soldiers find themselves under attack, pelted by missiles and molotov cocktails. In the confusion, they beat a chaotic retreat, leaving Gary behind to the fate of the vengeful mob. Fortunately, an older woman takes pity, saving him from the worst of their violence and he makes a run for his life. But what are his chances of survival in such violently combative streets?

We rated Jack O’Connell’s ultra-disturbing turn in Starred Up and he continues to impress here, a master of maximum conveyance with minimal dialogue. Gripping and shot with frightening intensity and immediacy, it captures the terror and animalism of the gang mentality – whether in Northern Ireland or any other political hotspot.  Just don’t get so traumatised that you forget to stop by Paddy Power for a quick flutter on the way home
