Wright sets this up an inspiring drama, which culminates in Churchill’s watershed ‘we shall fight them on the beaches’ speech, which we also heard at the end of Christopher Nolan’s Dunkirk. In fact, Darkest Hour works as a nice companion piece to that film. Unlike Nolan however, Wright opts for easy sentimentality. McCarten invents a scene in which Churchill takes the tube for the first time in his life and finds strength in the courage of ordinary Londoners. It’s so cheesy that a B-grade Bollywood director would have rejected it. But there is enough to enjoy here. Especially Oldman’s towering achievement.

Oldman’s Churchill is a terrific imitation, and will probably get him his first Oscar, though I’ll probably remember him as the sphinx in Tinker Tailor Soldier Spy or the punk in Sid and Nancy. As for Wright, I’d take the unbroken five-minute tracking shot along the beach at Dunkirk in his Atonement over the rousing flatteries of Darkest Hour.

Gary Oldman ceases to exist with his powerful performance as the former English Prime Minister…
