Louis Theroux.

I really like documentaries, and BBC's Louis Theroux produces some of the most entertaining pieces of work I have seen. He gets right into the lives of some sick sick people, weird people, 'interesting' people... and does it in a way that makes the subjects of his docos feel like they are able to be themselves in his presence. He is very unassuming, very sweet and plays naivety to a T. His series follows him while he hangs out with British men purchasing Thai brides, pickets American soldiers' funerals with the Westborough Baptist Church family, goes on safari in wildlife farm enclosures in South Africa with big fat white Americans hoping to shoot a zebra and chills with some Nazi families, talking to them about raising children... and that is only to mention a few of his classics!
