I highly recommend Errol Morris's film "Mr. Death: The Rise and Fall of Fred Leuchter." The film provides a disturbing insight into the pseudoscience behind Holocaust denial.

Fred Leuchter constructed and repaired execution equipment for a number of states. When Ernst Zundel was put on trial in Canada, Leuchter became the star witness -- and was promptly shot down. The man went to Poland, vandalizing the remains of Auschwitz, then sent "rock samples" to a lab.

Originally Morris was only going to feature Leuchter himself, thinking the man was so far out in space that any audience would realize how unscientific his approach was. Then historian Jan Van Pelt suggested that he present a counterpoint, since irony is a very dangerous tool, since not everyone gets it.
