John Simm in Prey; Privacy at the Donmar; Simon Armitage's Troy; Exhibition; Chris Marker

Privacy is a new play at London's Donmar Warehouse, looking at the way we inadvertently give away valuable private information through our use of modern communication technology - phones, computers. Is this a surprise?

Director Joanna Hogg's third film, Exhibition, continues her exploration of a very British awkwardness in the ways we relate to each other and our environment. It's a quiet film but does it have an important message?

The Last Days of Troy is Simon Armitage's theatrical reimagining of Greek Legend; telling timeless tales in modern language.

John Simm plays a policeman framed for a crime he didn't commit and determined to clear his name in Prey. The creative team behind it have tried to make it edgier and visually unconventional. Is it a cut above the usual police drama?

Chris Marker was a French artist whose work influenced film-makers including Terry Gilliam and James Cameron. An exhibition at London's Whitechapel Gallery looking back at his life is crammed full of imaginative peculiarities and controversial items.
