Natalie Portman as Nina Sayers – Black Swan (2010)
“I just had a hard day.”
Natalie Portman was already known for her small and petite figure even though she is fairly tall, but in this film, she pushed that to the point where she felt she might actually die.
Not only did she reduce her diet to little more than carrots and almonds to lose 20 pounds, but she would also spend 8 hours every day in rehearsals learning her moves and lines for the film.
Portman even dislocated a rib during rehearsals. She is quoted as saying “It was the first time I understood how you could get so wrapped up in a role that it could sort of take you down.”
