Warner Bros. is in talks with Marion Cotillard, Cillian Murphy and Ellen Page to join the cast of "Inception," which Christopher Nolan wrote and will direct as his next film.
Leonardo DiCaprio has already been set to star.
Production begins this summer for 2010 release.
The subject matter has been kept under tight wraps, with the studio describing the film as a contemporary sci-fi actioner set within the architecture of the mind.
Nolan will produce with Emma Thomas.
The film is Nolan's first with Cotillard and Page, but he is reteaming with Murphy, who played the villain Scarecrow in "Batman Begins," with a cameo in "The Dark Knight." Murphy just completed "Peacock" and "Perrier's Bounty."
Page just teamed with Murphy in "Peacock" and starred in the Drew Barrymore-directed "Whip It!"
