Yup, Black Swan is definitely full steam ahead now. According to THR, Mila Kunis is close to joining the film to play Natalie’s rival. Here’s their take on it.

The actress is in discussions to star opposite Portman in Darren Aronofsky’s supernatural drama “Black Swan.” The pic centers on a talented ballerina (Portman) in the New York City Ballet who is tormented by a rival who might or might not be a figment of the dancer’s imagination.

Kunis will play the rival, Lilly, with strange occurrences between the two increasing as they prepare for a big performance.

“Swan” is set to begin shooting in the fall in New York. Aronofksy’s Protozoa Pictures is producing with Mike Medavoy’s Phoenix Pictures. The project is being financed independently, with Michael London’s Groundswell Prods. believed to be one of the lead financiers.

The project does not have distribution, but Fox Searchlight, which distributed Aronofsky’s “The Wrestler,” could come on board as it moves into production.

I think Mila is really gorgeous and a pretty good comedic actor, but this will really be stepping out of the box for her. But I have faith in Darren Aronofsky. The dude got a great performance out of Marlon Wayans for crying out loud.
