Another chance to see one of Louis Theroux's most famous documentaries as the journalist looks back on his interview with children's entertainer Jimmy Savile following the revelations that he was a predatory sex offender. 15 years on from the original BBC documentary 'When Louis Met Jimmy', Louis Theroux sets out to understand how a man who was at the centre of British entertainment and charitable fundraising for decades was able to get away with a long litany of crimes. He talks to some of Savile's victims and people who worked closely with him and re-examines moments from his interview with Savile as well as footage that's never aired before on television.
