To anybody who watched TWTWB: Remember Moo Chul, the goon? The guy we were calling The Vulcan because of his ears? He's playing King Seonjo now! Check him out in the new historical series Jingbirok! And at least for now he's playing Seonjo in the same sort of way he played Moo Chul.
Not sure what to think of this yet but it's a fascinating piece of casting.
