They join previously announced cast members Natalie Portman and Mila Kunis.
Natalie Portman stars as Nina, a veteran ballerina who finds herself locked in to a competitive showdown with a rival dancer named Lilly (played by Mila Kunis) "with the stakes and twists increasing as the dancers approach a big performance." Nina is not sure whether her rival is a supernatural apparition or if she is having delusions.
The film will soon start production in New York City.
