In the first among 10 best anti-religion documentaries of all time is again, believe it or not, the documentary of Richard Dawkins! He made The Enemies of Reason in 2007 and just by reading the title, you could sense the anti-religious affection in it. Besides himself, other stars of the documentary are Derren Brown and Deepak Chopra. Once again, instead of the trailer you can see one part one of this amazing documentary.
