Inception

Inception is a 2010 science fiction action film written and directed by Christopher Nolan, who also produced it with Emma Thomas, his wife. The film stars Leonardo DiCaprio as a professional thief who steals information by infiltrating the subconscious of his targets. He is offered a chance to have his criminal history erased as payment for the implantation of another person's idea into a target's subconscious. The ensemble cast includes Ken Watanabe, Joseph Gordon-Levitt, Marion Cotillard, Elliot Page, Tom Hardy, Cillian Murphy, Tom Berenger, Dileep Rao, and Michael Caine. After the completion of Insomnia in 2002, Nolan presented to Warner Bros. a written 80-page treatment for a horror film envisioning "dream stealers," based on lucid dreaming.
