Orson Welles once described himself as a ‘king’ actor. Ralph Fiennes seems born to play dukes: nearly all his screen characters, even the crooks and madmen, share an imperious quality that goes with a kind of stony reticence. It felt natural that he should make his film directorial début with an adaptation of Coriolanus (2011), one of Shakespeare’s most misanthropic tragedies, in which he played the lead role of a Roman general with a frank contempt for the mob.
