The film's producers said Friday that Fiennes will star alongside Emily Mortimer in the movie, which is billed as a dark tale of sexual obsession based on Fyodor Dostoyevsky's "The Idiot." Scheduled to shoot in the fall, "Norma" marks the feature debut of writer-director McKay, who has known Fiennes for more than 10 years since the actor's days at the Royal Academy of Dramatic Arts. The movie also will include Emily Blunt in the cast and will be produced by Eliza Mellor ("I'll Sleep When I'm Dead") for U.K. indie television and film production banner Company Pictures.
