With the clacking of a typewriter, Darkest Hour echoes Atonement, Joe Wright’s earlier (and more impressive) foray into World War II drama. The bravura moment of that film was an extraordinary long take of the British troops trapped at Dunkirk, the focus of Christopher Nolan’s award botherer. Darkest Hour presents the time of Dunkirk from another perspective – that of Parliament in May 1940 as Winston Churchill (Gary Oldman) takes the office of British Prime Minister while Europe collapses before the Third Reich. Winston faces multiple challenges as he tries to wrangle survival for the troops and also protect his own position. Oldman is superb, unrecognisable in remarkable makeup yet never appearing to be a man in makeup. From his voice that wanders from quavering to strident (more varied than Brian Cox’s equally powerful turn), Oldman brilliantly portrays a career politician who understands the game of Westminster and only plays it his way. As a character study the film is effective and compelling, and Wright uses some thrilling cinematic effects such as long takes that travel around the House of Commons and overhead shots that range from Winston working furiously in bed as well as beleaguered British soldiers in Calais. At other times, however, the drama feels overdetermined, such as the machinations of Neville Chamberlain (Ronald Pickup) and Viscount Halifax (Stephen Dillane) as well as a sequence on the London Underground when Winston performs a mini-referendum on relations with Germany. This speaking to the people raises the interesting question of how to view the film through the lens of Brexit. There may be a temptation to adopt Darkest Hour for nationalistic propaganda, its depiction of a time when Britain stood against Europe calling for Britain to stand against the EU in these uncertain times. Equally, one can see Darkest Hour as a call for unity across borders in a time of division and mistrust, a point emphasised by Winston’s rallying of MPs even as the War Cabinet plots against him. For all its flaws, Darkest Hour still offers much food for debate, be that Parliamentary or otherwise.
