Movie: V for Vendetta (2006)
The typically cute and pixie Portman shaved all of the long brown locks off that contributed to her girl-next-door image ror the dystopian thriller about the struggle against a totalitarian society. As Evey Hammon, Portman buzzed her hair off in a scene in which her character is tortured. On top of critical acclaim, the actress also received a number of compliments on how she's one of the few women who can make a shaved head look sexy.
