The 44-year-old actress, who takes on the title role in a new biopic "Diana", prepared hard to alter her own features and replicate the tragic British royal's look, reported Contactmusic.
"I didn't just want to appear like her, it's also about the tone of her voice and the way she moved her face. It's completely opposite of how I move my face. I move my face on the right-hand side and she moves hers to the left," she said.
The actress spent weeks trying to get Diana's accent, confessing she was nervous about accurately playing the dead royal.
