Three outstanding actors, Marion Cotillard, Cillian Murphy and Ellen Page, are in talks with Warner Bros. to join Leonardo DiCaprio in Christopher Nolan’s Inception. Nolan will write and direct the film as well as produce it.

Production starts this summer for 2010 release.

The storyline is hush-hush, but the studio hints at a contemporary sci-fi with action set within the architecture of the mind.
