No. I learned everything I need to know about fictional early Christianity from "The Life of Brian".
Now that was a great movie! Incidentally, it contained quite a bit of fact, such as there being numerous wacko cults (though they did not necessarily believe what was presented in the film), the long list of factual things that answered the question:
what did the Romans ever do for us?, etc. The film also displayed a good deal of insight into human psychology and gullibility, though obviously presented in a satirical rather than literal way.
I strongly recommend the Criterion version of it, as it has some great deleted scenes that, in my opinion, should not have been deleted. Usually, when viewing deleted scenes, I think the makers of a film made the right decision, but not in this case. They are great.
