Casting request

I'm only one vote but Tony Curran gets it for the role of Jamie Fraser. I mean GOOD LORD! Look at him! Did Diana's Jamie come from seeing Tony or is it just coincidence? Scots, red mane, piercing blue eyes, knife-sharp nose, tall, warrior-like. Yummmm. So much emphasis is spent on his appearance and mannerisms in the books; why cast someone who doesn't possess them?
