@Psychedelic_Zebra – I disagree. A movie starring Richard Dawkins will help religious fundamentalists recruiting new members. They love the DVD. At least this is my hypothesis, see my recent Fluther question

Shermer is an outspoken advocate of skepticism. And he warns people not to fall into the trap of pseudohistory. He lists 25 reasons why people believe in weird things, for example
Theory Influences Observations — When you have a theory of something, you interpret the results inside your theory. So when Columbus arrived in the New World, he saw Asian spices and roots. His theory said he should be in Asia.
This means: Some atheists support the theory that the world would be a better place without religion. If Jesus didn’t exist, the Christian religion loses its foundation.
Bold Statements Do Not Make Claims True — L. Ron Hubbard called Dianetics “a milestone for man comparable to his discovery of fire and superior to his invention of the wheel and the arch.” But it wasn’t. The more extraordinary the claim, the more extraordinary well-tested the evidence must be.
This means: Jesus myth hypothesis is a bold statement and only a minority of historians currently support it. We need extraordinary well-tested evidence.
Emotive Words and False Analogies — Loaded language can be used to provoke emotion and obscure rationality. Industry can be called “raping the environment” or abortion “murdering innocent children” or a political opponent a “communist.” Rarely does this further rational thought, but clouds the issue with emotion and rhetoric.
This means: Richard Dawkins is part of the DVD. He’s a genius not only in biology, but also in rhetoric and polemics and emotive words. He is the role model for atheist fundamentalists (see also the Fluther question mentioned above).
Hasty Generalization — Also known as prejudice, or drawing conclusions before the facts warrant. A couple of bad teachers and it’s a bad school. A couple of bad cars and that brand of automobile is unreliable.
This means: Many atheists claim that all theists are superstitious. They also claim the bible is a dangerous book because it contains statements that appeal to people to commit genocide.

Historians use scholarly methods, see for example

My (computer scientist) interpretation of all this:
The probability that Jesus is a real historical figure is 98% or more. But the very essence of science is questioning itself all the time. This applies to history as well. More research is required to confirm or refute the Jesus myth hypothesis.
This does not mean that everything recorded by the four evangelists is exactly what Jesus said or did. There is a gap between Jesus’ life and the writing of the New Testament.
