Louis Theroux reveals the one thing that fascinates him about Donald Trump

Louis Theroux has revealed the one thing that fascinates him about Donald Trump.

The documentary filmmaker, who is currently working on a long-term project about the President's supporters, revealed he finds it tough not to marvel at his “shamelessness."

He told The Guardian : “Trump saw through so much. For all his awfulness, I can’t but help admire his shamelessness, in an odd way. Or maybe not admire, but be fascinated by it and maybe envy it. In a shame culture he seems to have figured out that if you refuse to be shamed, it gives you enormous power.”

On how the forthcoming documentary will alongside his past ones, Theroux continued: “I’ve always been fascinated by fringe beliefs and taboo attitudes, and some of those attitudes are creeping towards the mainstream. At that point, it stops being called weirdness. In a sense, weirdness is a majoritarian phenomenon. If enough people believe it, it stops being weird.” Theroux's latest film Dark States - Heroin Town aired on BBC Two last night (8 October) showing him visit a town in West Virginia that has a “fatal overdose rate 13 times the national average.”

The special is one of three documentaries that will focus on “uniquely devastating challenges“ prevalent in America including Murder in Milwaukee and Sex Trafficking Houston . Considering filming began before Trump took office, the specials are not designed to wade in on the country's political climate.
