Louis Theroux is set to release a new BBC documentary series which will see him revisit the stories that have impacted him the most over his 25-year career. 

The four-part series called ‘Louis Theroux: Life On The Edge’ will feature moments that viewers have never seen before.

He will also show viewers his journey to become one of the UK’s most renowned investigative reporters. 

The episodes will see new interviews with Theroux and some of his contributors from previous documentaries, to explore how their stories have developed since first meeting him. 

The 50 year-old, who has won two British Academy Television Awards said: "For years I've wanted to go back and make sense of the programmes I've made, find out what happened to some of the contributors, update their stories, and see what all these many hours of making TV might add up to.

"Lockdown gave me the time and space to do this. It's been a strange and fascinating couple of months working on this, and especially fun to dig through old episodes of Weird Weekends – programmes I made in the mid-'90s, when the world was a very different place.

“I'm really proud of what we've been able to do with this new series. I think we've been able to make the whole add up to more than the sum of the parts and to bring out surprising themes and commonalities. And, if nothing else, it was an interesting review of how my haircuts and glasses have changed over the years.”

Theroux has investigated topics surrounding Jimmy Savile, US neo-Nazi’s and Michael Jackson.

The release date for the series has not yet been announced.
