13. MERYL STREEP

Movie: The Iron Lady (2011)
Streep, one of the greatest actresses ever, becomes Margaret Thatcher in The Iron Lady —her gap-teeth and accent included. There is already talk about Streep picking up her third Best Actress Oscar for the performance, though she needed convincing before taking the role. Streep reportedly did not agree with Thatcher’s policies and, we suspect, hairstyle choice.
