Jennifer Lawrence and her unwashed hair
One might argue that Jennifer Lawrence got her first big movie role because she came to the audition with a runny nose and really dirty hair. She did this on purpose, in order to get into the character of a 17-year-old girl from a dysfunctional family. At first, the director of the drama, Winter’s Bone, dismissed Lawrence’s bid for the part, thinking she was too pretty. But the aspiring actress was not to be stopped!
Lawrence was so eager to star in the movie that she flew to New York, intentionally walked 13 blocks through sleet, and showed up for the audition not wearing any makeup and with a head of hair that she hadn’t washed for a week. As a result, she got the coveted role.
