He is reportedly in talks with British actor Christian Bale to take on the role of Noah for the $130m flick.
Aronofsky and Bale already have experience of working together. Aronofsky directed some scenes in The Fighter, which earned Bale an Academy Award for Best Supporting Actor.
The Black Swan director is keen to make the film and doesn't see why any movie studio wouldn't want to back it.
"I think it's really timely because it's about environmental apocalypse which is the biggest theme for me right now for what's going on on this planet," he told Slash Film.
"So I think it's got these big, big themes that connect with us.
"Noah was the first environmentalist. He's a really interesting character.
"Hopefully they'll let me make it."
