Natalie Portman is attached to star in Darren Aronofsky’s thriller Swan Song, according to The Hollywood Reporter. The supernatural thriller about a New York City ballet dancer has gone through several incarnations since initially being set up at Universal in early 2007, but Portman’s involvement could help it finally get made. John McLaughlin’s original script also underwent a rewrite by Mark Heyman, a development executive at Aronofsky’s Protozoa Pictures. The story follows a veteran ballerina (Portman’s role) who finds herself in an intensely competitive situation with a rival, who may be either an apparition or a delusion. The film could start shooting as early as this year.
