What puzzles me when I see pictures of real life Sam Heughan, is how the casting guys could see Jamie in him. As Jamie he looks so different. It is not only the hair, the makeup, but his face wears a kind of darkness that doesn’t show when he is not acting. I know this is the actor’s job, but how could one anticipate such a transformation amazes me, I would never have guessed (no wonder casting is not my job).
I know that even Diana Gabaldon said that when she saw pictures of SH she didn’t agree with the choice that had been made and that it’s the audition tape that conviced her. It must have been a hell of a good audition because I am not sure I would have been able to perceive the character in him and I would have been wrong because IMO he makes a good Jamie.
