The very lovely Mila Kunis has joined Natalie Portman in the Darren Aronofsky directed thriller, The Black Swan. Portman will play an elite ballerina, who is badgered by another ballerina, to be played by Kunis, who may or may not be a figment of her imagination. Aronofsky is apparently going full throttle ahead on this one, which has left his previously announced gig helming a Robocop reboot in serious limbo. The Hollywood Reporter are saying that funding studio MGM are now looking for another a director, which is bad news, as Aronofsky was the main reason it wasn't a travesty that the remake was happening in the first place. Still, The Black Swan sounds pretty cool all the same. Portman is currently up north in Belfast shooting Your Highness with Danny McBride and James Franco.
