Religulous
Religulous is American comedian Bill Maher's documentary about his search for the reasons for faith. Maher interviews Muslims, Jews and Christians Mormons, scientists and even a Vatican astrologer to try to understand why people have faith. He visits a Creationist museum, which shows dinosaurs and humans living together, and even the Holy Land theme park in Florida where they enact recreations of Jesus being crucified on an hourly basis!
