The brutal gang rape and murder of a student on a bus in Delhi in 2012 provoked widespread shock and outrage and put the spotlight on violence against women in India. A recent documentary about it called India's Daughter provoked huge controversy. It featured an interview with one of the five convicted rapists expressing no remorse and blamed the victim for fighting back. The Delhi government banned the film in India. HARDtalk talks to the documentary's director Leslee Udwin and asks her if her film was sensationalist.
