One of the issues that some people have had with Darren Aronofsky’s Noah — it was never a big-enough deal to become a full-fledged controversy, per se — concerns the ethnicity of the actors.
The film depicts the annihilation of the entire human race, except for one family that will go on to produce the entire human race as we know it today — so it seems a little odd to some people that pretty much every character we see in this film fits into a single ethnic category, i.e. Caucasian.
It seems even more odd when one considers that the human race originally had dark skin and then evolved lighter skin as some population groups “migrated away from the tropics . . . into areas of low UV radiation” and “developed light skin pigmentation as an evolutionary selection acting against vitamin D depletion.”
