II.  As an investigator of unusual claims, James Randi is accustomed to being confronted with incredible examples of medieval thinking in the modern age. A good example is the recent worldwide fascination with a black-and-white film on TV, which purported to show the dissection of an alien from outer space. The TV network that broadcast this film reportedly paid $100,000 for this “cinematic miracle,” which was hailed by UFO fans as conclusive proof of the existence of extraterrestrial beings. “The film was so inherently flawed,” scoffs Randi, “that even I was amazed at the fact that anyone could accept it. This film, which should have changed the course of history, is now relegated to the vast gallery of embarrassing mistakes.”
