11 Actresses Who Completely Transformed For Roles, And Lost Their Long Locks On The Way

Today is Nov. 5, also known as Guy Fawkes Day, a British holiday that commemorates the Gunpowder Plot, in which the titular conspirator attempted to blow up Parliament in 1605. The political event is a central point of the Wachowski siblings' 2006 film, "V for Vendetta," where Natalie Portman's character, Evey, recites a famous rhyme about Fawkes.

In honor of the 5th of November, and Portman's emotional shaved-head scene, we're looking back on all the actresses who rocked a buzz cut for their film roles:
