Guy Lodge Film CriticFemale directors and actors reigned supreme at tonight’s San Sebastian Film Festival awards ceremony, with the Romanian actor-turned-director Alina Grigore taking the Golden Shell for Best Film for her intimate debut feature “Blue Moon.” The film, a raw realist study of a young woman attempting to free herself from an abusive rural household, was an unexpected winner, besting a number of higher-profile auteur films in the festival’s main competition.
