Attack It

As ballet teacher Vincent Cassel yells for her to "attack" the dance, Natalie Portman is thrown off her spin by Mila Kunis.

Kunis plays Lily,  a fresh off-the-plane rival for Portman's role as the Swan Queen. The actress has said that she worked out seven days a week for up to five hours at a time to lose the 20 pounds she needed to for the role.
