Louis Theroux’s Forbidden America

BBC2, 9pm

Louis Theroux's Forbidden America: Theroux has said the series will look at the way that social media “has affected people in America who are in different ways involved in dangerous, extreme, or morally questionable lifestyles”.

New three-part series. Louis begins with an investigation into the far right, which was thrust into the international spotlight following the notorious Capitol Hill riots in 2021. He learns how the leaders are building solidarity through online networks, and how the movement is emerging from the darker corners of the internet to influence events in the ‘real’ world. Other episodes look at  rappers and porn performers.
