Lee Miller, Imperial War Museum

What a woman. Does the news that Kate Winslet is to play the polymath Lee Miller in a Hollywood biopic mean a kind of sanctified apotheosis of Miller's quite extraordinary life? The story is so dramatic it transcends any fiction. Her path was controversial, imaginative, accomplished, and in many ways profoundly sad, an emotional roller-coaster. But the legacy is astonishing, as more and more of her achievement as a photographer is revealed.

Peter Lanyon, Courtauld Gallery

Free as air, but there was a very heavy price to pay for his ecstatic exploration of the sky by the Cornwall painter Peter Lanyon, who died in 1964, aged just 46, as a result of injuries received in a gliding accident. 

The Courtauld Gallery is known for its series of original, incisive, acute and intense exhibitions taking a sharply focused view of one aspect of an artist’s work. Often these provide a revelation and so it is here.

Jimmie Durham, Serpentine Gallery

The first thing you encounter is a ballot box bolted to the lid of a school desk; what or whom you might be voting for – apart from the hope of change – is not specified. In the eyes of Jimmie Durham, change is badly needed; in fact, most of the premises on which western society is built could do with a radical rethink. Judging by the state of the box, though – the lid looks as if it has been prized open and bolted down many times – fair and free elections seem unlikely.
