Natalie Portman will soon be heading to the United Kingdom to shoot David Gordon Green's "Your Highness" alongside Danny McBride and James Franco, but the project that could follow that comedy is now taking shape. According to The Hollywood Reporter, Portman has attached herself to Darren Aronofsky's "Black Swan."

A supernatural thriller set amongst the dancers of the New York City Ballet (really), the film was in development at Universal Pictures before the studio got cold feet on the project and let it go.  Now, with Portman agreeing to star if the film gets picked up, Aronofsky is pitching the film to specialty studios around Hollywood.  The film will find Portman playing a veteran ballerina who finds herself in a competitive situation with another dancer, but is this rival real, some sort of apparition or an insane delusion?

After the disappointing critical and audience reaction to "The Fountain," Aronofsky put his career back on track with last winter's "The Wrestler."  The acclaimed drama resulted in a career comeback Oscar nomination for star Mickey Rourke.  The filmmaker has been developing a "Robocop" remake with MGM, but if financing can be settled, "Black Swan" would be his next film.

Portman will be seen this fall in the delayed Jim Sheridan drama "Brothers."
