Oscars winners Jessica Chastain and Eddie Redmayne walk the red carpet at the world premiere of "The Good Nurse" at the Toronto International Film festival. The true-crime film follows the relationship between two nurses, one of them (Redmayne) being a serial killer and the other one a nurse who helped to arrest him. "To me, it was never just another serial-killer movie. It was a story about compassion, about charity, about being there for one another", says director Tobias Lindholm. IMAGES AND SOUNDBITES
