Actress had emotional scenes
The actress says director John Maybury encouraged her to connect with her depressive character.
The hardest scene, emotionally, for me was when I was crying and pulling stitches out, she tells the Daily Mirror.
John locked me in a trailer with the saddest music I’ve ever heard and said, Come out when you’re ready and kind of tortured me.
Sienna, 27, starred opposite Keira Knightley, 24, in the drama.
