'Career-wise, it gets no better than this,' Gabrielle recently told Ocean Drive magazine. 'It’s by far the smallest role I’ve ever taken, but easily the most challenging and the most rewarding.'

Her character ends up working in the main house, where she is violated by one of the plantation's white guests. 

'He sees her and feels entitled to her body,' she explained. 'What happens to her is one of the things that sets in motion one of the most successful slave liberations in the history of our country.'
