I read they made it into a kind of huge environmentalist propaganda piece, about how the flood was caused by humans' misuse of nature (who knows how Bronze Age humans could impact global weather...).
According to Big Hollywood, Aronofsky is going to take a different and to believing Christians and Jews an unsettling approach to the story. According to the director of the film due to open March 28, 2014, the story of Noah is not so much religious as it was environmental. Noah, in fact, was the first environmentalist.http://voices.yahoo.com/noah-movie-environmental-allegory-11233114.html
Earlier reports of the film expressed disapproval that Noah was depicted as being centered on an environmental agenda, and that Aronofsky viewed Noah as the “first environmentalist.” Noah is also stated to be tormented with guilt for surviving the flood while others perished. It is not known whether those particular aspects still remain in the movie at this time.
“It’s clear that Noah is not a Christian film,” writes the blog Beginning and End in a lengthy critique of the production.http://christiannews.net/2013/11/17/new-noah-film-starring-russell-crowe-flooded-with-controversy/
Then again, fealty to the original story isn't exactly Aronofsky's goal. He's said that the film is less about the classical teachings of the biblical narrative and more "about environmental apocalypse" because "Noah was the first environmentalist." After reading a draft of the script, Christian screenwriter Brian Godawa even called Aronofsky an "environmentalist wacko."
Paramount, which is financing the film, is allegedly not so happy with the green angle because it would prefer a picture it can market to faith-based audiences. In fact, the Hollywood Reporter wrote last month that the company had sparred over final cut with the director because "test screenings of various versions [produced] worrisome results."http://www.refinery29.com/2013/11/57379/noah-trailer-aronofsky
