Juno star Ellen Page, Oscar winner Marion Cotillard (La Vie en Rose) and Irish actor Cillian Murphy (Batman Begins), are in talks to join Leonardo DiCaprio in the top secret film, Inception, which will be directed by Dark Knight‘s Christopher Nolan, Variety reports. The plot and all details about the film have been closely guarded, but has been described as a sci-fi action film with connections to the mind. All three actors are in high-demand these days. Cotillard plays Johnny Depp’s lover in Michael Mann’s Public Enemies this summer, and Page and Murphy just finished filming the thriller Peacock together. Murphy played villain Scarecrow in Nolan’s Batman Begins and had a small cameo in last summer’s Dark Knight.
