Bad Zeitgeist timing - putting out a blockbuster with American stars playing Cold War Russians, with a reminder how near to nuclear war we were in 1961, and still are in 2002. No wonder Kathryn Bigelow's K-19: The Widowmaker nose-dived to the bottom of the US box office. It's not such a bad film, actually: visually very impressive and archaeologically stupefying. The K-19 nuclear sub, designed to give Nato a fright by loosing a test missile in the Arctic ice cap, leaked like a rain forest, bust its steel cladding under pressure and looked inside like a B&Q store full of faulty goods the home improvers had returned.
