Except he took the existing story and then
added a bunch of gratuitous sex and violence. The Bible comes with it's own.
I have been saddened though, at how impossible it would be to get investors to build a up a budget big enough to make a really slick movie of the Old Testament featuring all of the deranged, sick, perverted stuff it boasts.
'Cause it would be so funny, since most Christians haven't read the Bible, there would be an outrage, "Blasphemy!"...such as the psycho part where God commands the people to eat dung, or where the fat guy gets stabbed and it goes into detail about how he was so fat that the fat enveloped the hilt of the dagger ( that's so Troma

), or just show all the hundreds of times where God commanded his people to kill babies (which is funny, I remember how outraged all good Christians are about abortion, lol)and then you could go on the talk shows and show them every book, chapter and verse.
