Nick Nolte joins Darren Aronofsky's Noah

Darren Aronofsky's biblical epic Noah hits our screens in little under two and a half months, but the director is still announcing, on Twitter of course, a new cast member, with Nick Nolte signing on to play a Watcher, an eleven foot tall, six armed wingless angel who play a major part in the story. His character, Samyaza, obviously will be mostly CG, and was originally credited to Mark Margolis, but obviously Margolis has bowed out, meaning Nolte has stepped in. The announcement came with the below picture, and what has me most intrigued is the picture in the background. Could that be what the Watchers, who we have seen nothing of yet, look like in the finished movie?

Released: March 28 

Synopsis: Academy Award® winner Russell Crowe stars as Noah, a man chosen by God for a great task before an apocalyptic flood destroys the world.
