The star went to extremes for her role as a woman who seduces a Death Row inmate, played by John Cusack, and was left battered and bruised after shooting graphic sex scenes.
Cusack tells The Hollywood Reporter, ""I knew Lee (Daniels, the director) and Nicole were looking for a certain intensity. We shot the rough sex scene on day one, and I barely knew her.
""She never took a backwards step; working with her was working without a net. There's a lot more s**t in there that was cut out, believe me. I was afraid I was hurting her, but she was more fearless than me.
""The next day, Nic showed up with purple and blue bruises all over her legs! I said, 'Go put some make-up on your legs!'""
