VIDEO : Gabrielle Union Says She Understands Why Some People Will Not Go To See 'Birth of Nation'

Todd Williamson/Getty Images The Birth of a Nation cast received applause when they appeared on stage Friday night to introduce the film's two screenings at the Toronto International Film Festival. They received standing ovations when they reappeared on stage for Q&A's after the end credits rolled.
