That is a bit of the point a theologian was making on CNN today. If you made a movie of what was in the gospels it would be all done in a few minutes. The rest is a combination of added stuff with no history behind it and picking and choosing from what is in the different gospels.
One thing they were worrying about was that movie goers would think that this is history. "It is as it was" - kind of thing.
The Jewish representative was concerned about how the Jews were portrayed. I'll probably wait for the DVD to see it an I guess I'll have to reserve judgement until then.
My daughter might be interested as she did have a short term interest in comparative religions a couple or so years ago.
