DVD: Duplicity, Retail & rental, (Universal)

This labyrinthine espionage caper from the writer-director of Michael Clayton stars Julia Roberts and Clive Owen as two super-cool corporate spies who may be infiltrating Tom Wilkinson's pharmaceuticals company for Paul Giamatti, or may be doing the exact opposite.

As the title suggests, no one is to be trusted – the upshot being that it's hard to care who comes out on top. Still, Duplicity is glamorous and clever enough to keep you hanging on for a corking final twist.
