Among the many, many reviews of Noah, Brian Mattson has the most fascinating:
He identifies a number of overtly Gnostic themes in the film, rather well-executed under the guise of a biblical story. If I can get around to seeing the film, I will be interested to see how much of Mattson’s interpretation holds. I have had a longstanding interest in Gnosticism since my undergraduate days of religious theory and Simone Weil. I am both sympathetic and hostile, as my ambiguous love for Weil testifies.
