Ever noticed that everybody in movies and television has green eyes?
It's really weird once you start looking for it.
Like 3% of the world population have green eyes, but in TV shows it's like half.
Of course we see proportionately more white people and non-Asians on screen than there are in the world,
but there still seem to be a lot of green eyes.
I first noticed this on the TV show The Unit, but it seems to be the case whenever I start looking for it.
My theory is that is is a unconscious thing picking green eyed people in castings.
