Personal Quote:

[on the Night's King's (his Game of Thrones: Das Lied von Eis und Feuer (2011) character) design] It's actually molded off of my face - way back a few years ago we did a cast of me, and they basically created prosthetics to go onto my face, my arms as well and pretty much down to my chest. It seems like you just pop a mask on, but it's incredibly much more detailed.
