This year's mini-trend of Biblical epics includes Aronofsky's Noah and Ridley Scott's Exodus. But if the cards had played out differently, we could have seen Alex Proyas' Paradise Lost, based on Milton's poem about the fall of Lucifer. And judging from this concept art, it could have been the most lovely of all.
Paradise Lost, of course, wouldn't be a "Biblical" epic in the strictest sense, since Milton takes a fair number of liberties with the Bible story in his famous poem. (And then Proyas probably would have taken another bunch of liberties on top of that.) Lucifer would have been played by Bradley Cooper, in an interesting casting choice. Casey Affleck would have played Gabriel, Djimon Hounsou would have been Abdiel, the Angel of Death and Benjamin Walker would have been Michael.
