For BLACK SWAN (2010), Natalie Portman trained for over a year in ballet and spent months performing up to eight hours a day to prepare for Nina, the dedication paid off with an Oscars winning performance.

Black Swan saved Natalie Portman’s career.No director wanted to work with her after starring in the Star Wars prequel because everyone thought she was a 'horrible actress' Until, she has been nominated for 3 Oscars and won Best Actress for 'Black Swan'

Natalie Portman really shaved her head for that scene in V for Vendetta (2006).She called it a one-shot take and one of the most stressful moments of filming.Director remembers it differently, saying she loved it and kept rubbing her head afterward.
