Louis Theroux is a journalist and filmmaker who is not daunted by any topic.
Over the course of his career he's made programmes about paedophiles, drugs, Scientology, the Westboro Baptist Church and various other controversial aspects of society that most documentarians would make a point of avoiding.
However, his latest endeavour will see him revisit a subject matter that he has previously worked on, as BBC Two has announced that he will make a new documentary about Jimmy Savile.
Theroux spent several months in Savile's company back in 2000 as part of his 'When Louis Met…' series, but obviously that was before the one-time TV host's alleged dark past as a sexual predator was uncovered.
In this new documentary, he will talk to Savile's family, friends and work colleagues and investigate how he managed to get away with his crimes for five decades.
A press release from BBC Two's Controller Kim Shillinglaw said: "BBC Two should be part of the national conversation and this challenging subject matter is the kind I want to see on the channel. Louis Theroux is one of the country’s most talented filmmakers, and I am very pleased that he is revisiting this important – and deeply personal - subject for us, asking difficult questions about the life of Jimmy Savile and those around him and exploring the impact his crimes had on his victims."
