I would have loved to see Alex Proyas be able to make this Paradise Lost movie. It sounded like it was going to be awesome, and now we've got some really cool concept art done for the film that shows us what could have been.
Bradley Cooper (The Hangover) was supposed to play Lucifer in the film, which was to be based on the epic 17th-century poem by John Milton. It would have been an epic-sized movie about good vs. evil, and it tells the story of the war in heaven between archangels Michael and Lucifer, including the latter's role in Adam and Eve's fall from grace. Here's the official synopsis:
Lucifer and Michael, God's greatest archangels, share the bond of extraordinary friendship until God produces his greatest creation: Man. Unable to remain subservient to God if it means bowing down to humanity, Lucifer begins his dark descent and is cast out — only to plot his revenge.
This thing could have been completely badass! It's a shame that it will never happen. Check out the concept art created by artist Brian Matyas.
