Margot is great at playing bad girls. But in the historical drama, Mary Queen of Scots, which tells the story of Mary I Stuart and Elizabeth I, Margot Robbie is a very different actress. Not only did she nail the role, but she also went through physical transformations like when she had to undergo a 4-hour-long makeup session to make her face look like it was infected with smallpox. As it turns out, she’s not afraid of feeling ugly on-screen.
