Whatever religious beliefs John Huston did or did not have, he treated the Scriptures with a great deal of respect. I don't see why an atheist would do a movie like this in the first place. I would think he wouldn't have wanted to touch it. But the beauty and poetry of this film is simply awesome. I would have given it ten stars, but he did take some artistic license with Scripture and he did kind of ham it up in the Noah's Ark sequence. Also, he left out the part where Noah got drunk after the flood and cursed one of his sons because they made fun of his nakedness. Otherwise, this is a beautiful film. It reminded me a little bit of HOW THE WEST WAS WON, in that he chronicled a few generations in this story, and many of the actors had little more than cameo appearances. The Creation scenes were absolutely gorgeous. I read somewhere that he didn't want to use animation drawings for the Creation, because he felt that the world was in a constant state of creation, and he had a crew film some of the wonders of the world at work. The results are stunning. The world really looks fresh and new in this film. You can tell he put a lot of care in making this film.
As a musician, I have to comment on the music in this film. It is as beautiful as the film. Too bad the soundtrack is out of print now. I had the album when I was younger and I played it nearly every chance I got. I never knew until I saw on this site that Ennio Morricone had a hand in writing some of this score (don't know which parts) but was uncredited. Instead, a Japanese composer named Toshiro Mayuzumi did most of this score, a composer I haven't heard of since.
Until PASSION OF THE Christ, this was the last of the big Bible epics and is an underrated masterpiece worth seeing. (THE LAST TEMPTATION OF Christ doesn't count because it took the Scriptures and butchered them.) 9 out of 10.
