Derren Brown is a magician who, in this special, uses classic stage techniques ("suggestion, psychology, misdirection, and showmanship") to examine various US belief structures and the naivete they run on. He's an outspoken atheist who has worked with Richard Dawkins and has a huge list of other TV specials, all of which sound just as clever as this one.
