Her performance in the film received praise from critics, and she garnered several nominations for her portrayal of James, including a Satellite Award nomination for Best Supporting Actress, and a NAACP Image Award nomination for Outstanding Supporting Actress. Beyoncé donated her entire salary from the film to Phoenix House, an organization of rehabilitation centers for heroin addicts around the country.
