I read about this at foxnews.com. It sounds very fascinating. I agree that the cruxifiction should show what Jesus went through. However, I hope that he gives just as much if not more focus on the glory of Christ's resurection from the dead.
As far as doing the whole thing in Aremaic and Latin, though artsy, I think thats stupid. The gospels had some pretty damn fine life lessons and film is a good medium to present them. Jesus' parrables and speeches were mind blowing. Why make it where people can not understand them.
