Back in 2010 those comparisons seemed absurd: how could the writer-director of classy-but-overthought superhero movies, as well as middling oddities such as The Prestige, be seriously thought of in the same bracket as the lambent mind behind Dr Strangelove, 2001: A Space Odyssey, A Clockwork Orange and Barry Lyndon?
