I didn't think he was particularly blue so much as he wasn't...well, right. When they showed his original picture it really strikes you how messed up he looks. At first he just looked like a guy who worked alternately in a mine and in the sun for 40 years and his hue was just a little enhanced from sniffing uranium. But then when they show what he looked like, it really stands out. I found the actual interview pretty inane so I cut it off after a few minutes.
