The difficulty with Thorin is that he enters the story on the edge of failure, but with everything to win. I remember thinking when I first read the scene for the casting, that here was a character who felt like a dying ember, yet with the energy and hope to reignite into the furnace that once powered this great warrior. But, he has all the potential to fail.
I connect personally with that last sentiment. I was never really sure if I could pull this role off; I felt secretly that many others also felt the same and it’s one of the reasons I could never sit down on set (I am a pacer, apparently). I could never rest.
