In ‘Tropic Thunder,’ Robert Downey, Jr. played Kirk Lazarus, a talented actor with a propensity for saying the wrong thing at the wrong time (and maybe even when not). Kirk’s character was an Australian actor who underwent a “pigmentation change” to darken his skin in preparation for a role as a Sergeant. This is just one example of how some people will transform themselves for a part in a film or television show, and it pokes fun at Hollywood.

Anne Hathaway’s diet for Fantine’s physique
In the musical Les Misérables, actress Annie Hathaway played Fantine, a prostitute. She also went on an extreme diet to play her role.

Anne Hathaway began her weight-loss journey in January 2012. She ate only two squares of oatmeal paste per day for three weeks, after which she lost 13 pounds. “It was definitely a little nuts,” she said about the whole experience. However, this was well worth it – Anne won several accolades, including the 2012 Academy Award for Best Supporting Actress.
