http://www.youtube.com/watch?v=DP-s3AV9Kzs&feature=PlayList&p=38D7709329F922B2&index=0&playnext=1This is an hour long British TV documentary about three child evangelists, two from the US and one from Brazil. Like Jesus Camp, it is pretty disturbing (especially part 2 around 1:00-3:40) and really shows what Richard Dawkins is talking about when he compares religion to child abuse. This one also talks about the commercial part of evangelism.
Maybe this is one for the idea bank for a movie night?
