Describing the “amazing challenge” he faces, Theroux continues: “The challenge with Trump would be... something so abhorrent that walks on two legs and is a human being, you have to explore where his foibles come from.

“Hopefully people will like it. It [will be] good.”

Theroux has form when it comes to approaching unlikeable topics. He famously met with the people of the Westboro Baptist Church (aka the “most hated family in America”), and, depsite challenging their opinions, earned their respect enough to engage them in thought-provoking debates and conversations.

Time will tell as to how he gets on with Trump.
