Tywin by Xavier
A reader named Xavier writes, "I couldn't help thinking about a fictional casting while I was "re-re-reading" A Song of Ice & Fire, discussing with some friends about actors past & present that would make perfect matches for your characters. At some point I tried to create one of them in CG. If you would mind to have look, I hope you could fancy it, and eventually guess the actor I tried to mimic."
I'll leave it to my other readers to guess your actor. Myself, I'd love to see Tywin played by Kurtwood Smith (as in DEAD POET'S SOCIETY) or Robert Duvall (THE GREAT SANTINI).
