Mila Kunis hunts 'Black Swan'

Starring opposite Natalie Portman in Aronofsky's drama

SAN DIEGO -- Mila Kunis will be Natalie Portman's nemesis.

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.

Kunis, who broke out with her role as Jason Segel's love interest in last year's "Forgetting Sarah Marshall," was among the standouts at Comic-Con during the weekend. The actress, repped by CAA and Curtis Management, turned out to promote turns in Denzel Washington starrer "The Book of Eli," the Ben Affleck-toplined comedy "Extract" and her voice role in the animated Fox series "Family Guy."

Kunis also is set to co-star in the relationship comedy "Date Night" alongside Steve Carell and Tina Fey.

"Swan" is set to begin shooting in the fall in New York. Aronofksy's Protozoa Pictures is producing with Rick Schwartz's Overnight Prods., which is financing the indie. Overnight's Schwartz and Aaron Kaufman will produce with Protozoa's Scott Franklin, while Phoenix Pictures' Mike Medavoy will exec produce.

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