The story of Noah's Ark is found in the sacred literature of three of the world's religions, so it is familiar to 54% of the world's population; over 38 billion people. This would seem an ideal platform from which to convince people to spend money to see a big-budget movie of it. Surprisingly, in order to make it "popular", its director resisted having God mentioned in the script.
I guess this is why I wasn't a marketing major.
