I don't intend to troll the show any more than he did himself. I'm just wondering what are the similarities and differences between Lan in the book and Lan in the series.
According to R.D. Malkier's last king is a large man 196 cm tall, muscular, with slightly gray hair and icy blue eyes. Next to the little one, Aes Sedai looks huge.
But what is Rafe Jutkins' vision:
Lan is a petty nimble warrior with a mixed vision of a Korean-Japanese sensei. As tall as Moiraine even at times she towers over him.
This is not about Daniel Henney, but about the screen presence of the character, which is to put it mildly quite lean.
