Mila Kunis (Forgetting Sarah Marshall) is in talks to star opposite Natalie Portman (The Other Boleyn Girl) in director Darren Aronofsky’s Black Swan, according to the Hollywood Reporter. Kunis, who will appear opposite Denzel Washington in the upcoming post-apocalyptic thriller The Book of Eli, would play a rival ballerina who may or may not be a figment of Portman’s character’s imagination in the supernatural drama. The film would be Aronofsky’s first since his acclaimed, Oscar-nominated turn with The Wrestler.
