My son took me to see a high school play recently, and I noticed that among the cast, the pretty/handsome/hot kids had the lead roles, and the cast was on average prettier than the supporting crew. I mentioned this to my wife, who was in drama club in high school, and she told me this was one of those things everyone knew – others would try out, but the prettiest kids were favored. The effect is strong, stronger than could be explained by a weak correlation between acting ability and prettiness.
