Christopher Nolan has form when it comes to films about wilful self-deception and the unreliability of our own minds – Memento (2000) was a striking account of an amnesiac using polaroids, tattoos and notes-to-self to hunt down his wife’s killer. With Inception he turns his protagonists’ minds loose in the world of dreams, a shifting labyrinth in which he builds a movie at once structurally and psychologically complex and edge-of-your seat thrilling.

Cobb (Leonardo Di Caprio) is a corporate thief with a very particular skill set: he can break into dreams and steal the dreamers’ secrets. But when one of these burglaries goes wrong, he finds himself hired to pull off the ultimate job – not stealing an idea, but this time implanting one.
