Darren Aronofsky is still recruting some ladies for his upcoming supernatural thriller "Black Swan," and the latest to join the party: Winona Ryder. Mila Kunis and Natalie Portman are also on board.

Portman plays an experienced ballerina who's having a hard time dealing with a rival dancer (Kunis). As the story develops, Portman's character is not exactly sure whether what she sees and experiences is real.

Variety says Ryder will play a fellow dancer. /Film also reports Vincent Cassel and Barbara Hershey are set to join the project.

John McLaughlin wrote the original script for "Swan," which Mark Heyman rewrote. Aronofsky recently helmed "The Wrestler," which I absolutely adored.

Ryder, who was last seen in "Star Trek," has "The Private Lives of Pippa Lee" coming soon. Kunis will soon be seen in "The Book of Eli," and Portman has "Brothers" coming out soon.
