Mike Cahill's Another Earth was one of the most thought-provoking and gut-punching indie movies of the last few years. And now Cahill is back with I Origins, a complex thriller about the origins of life that's already sparking lots of debate. And we've got nine exclusive images!

Here's the official synopsis of I Origins, which hits theaters on July 18:

I ORIGINS, the second feature film from writer and director Mike Cahill, tells the story of Dr. Ian Gray (Michael Pitt), a molecular biologist studying the evolution of the eye. He finds his work permeating his life after a brief encounter with an exotic young woman (Astrid Bergès-Frisbey) who slips away from him. As his research continues years later with his lab partner Karen (Brit Marling), they make a stunning scientific discovery that has far reaching implications and complicates both his scientific and spiritual beliefs. Traveling half way around the world, he risks everything he has ever known to validate his theory.
