Interesting. This is the the kind of thing I would expect Louis Theroux would cover, but I guess he's on to more serious sociological topics now, like poverty and crime, instead of just the weird.
Is he? That's both good for him and sort of a shame-- I've got a bunch of episodes of Weird Weekends, and they're great. His ability to keep composed is pretty amazing/enviable.
Yes, it doesn't seem that they have released any of his DVDs in Region 1 yet, but it did seem last time I checked that many of his documentaries were on YouTube, including the newer ones where he goes to the slums of Philly and Johannesburg or prisons. He has also released two books. The first
The Call of the Weird I have and would recommend, but the other one,
May Contain Traces of Nuts was supposedly published in January but I can't find it anywhere on the web.
