The problem is of course that Aronofsky wants to make a movie "inspired by" the Noah's Ark story, and he can't understand that a lot of Christians (and Jews!) would have a problem with him taking "artistic" liberties with it.
The trouble began when Paramount, nervous about how audiences would respond to Aronofsky's fantastical world and his deeply conflicted Noah, insisted on conducting test screenings over the director's vehement objections while the film was a work in progress.
Friction grew when a segment of the recruited Christian viewers, among whom the studio had hoped to find Noah's most enthusiastic fans, questioned the film's adherence to the Bible story and reacted negatively to the intensity and darkness of the lead character. Aronofsky's Noah gets drunk, for example, and considers taking drastic measures to eradicate mankind from the planet. Hoping to woo the faith-based crowd, Paramount made and tested as many as half-a-dozen of its own cuts of the movie. "I was upset -- of course," Aronofsky tells The Hollywood Reporter in his first extensive interview about the film's backstory. "No one's ever done that to me."
By contrast, Aronofsky would never make the same mistake with the Koran, I'm sure. Or if he would, his backers wouldn't.
