Black Swan

Darren Aronofsky’s psychological thriller was one of the most celebrated films of 2010, earning five Oscar nominations including Best Picture. Natalie Portman won Best Actress for her portrayal of Nina, a perfectionist ballerina who slowly loses her sanity when her role as the Black Swan in “Swan Lake” becomes a reality. Though Portman’s body-double claimed to do most of the dancing, Portman not only endured vigorous training with choreographer (and fiancé) Benjamin Millepied, but also lost 20 pounds for the role.
