In a world where technology exists to enter the human mind through dream invasion, a single idea within one's mind can be the most dangerous weapon or the most valuable asset.

Cryptically described as a contemporary sci-fi action thriller "set within the architecture of the mind", this is director Christopher Nolan's follow-up to smash-hit The Dark Knight.

Leonardo DiCaprio is Dom Cobb, an expert in "subconscious security". He's a high-tech agent who steals ideas from his targets while they sleep, manoeuvring through their complex and surreal dreamscapes. Cobb's rare ability has made him both a coveted player in the world of corporate espionage, and an international fugitive. Now Cobb is offered one last job and the chance to get his life back. Instead of the perfect heist, Cobb and his team of specialists have to pull off the reverse: not steal an idea but to plant one.

His wife is played by Marion Cotillard, and Ellen Page is his intern sidekick. Joining them are Nolan regulars Michael Caine, Cillian Murphy and Ken Watanabe. The film was shot around the globe, including Tokyo, Los Angeles, Paris and London.
