Respuesta: Canción de Hielo y Fuego [HBO-BBC]
Martin ya lo ha confirmado en su blog. Esto es lo que dice sobre Rory McCann como Sandor:

"A lot of good actors auditioned for the role, and several gave really first class readings... but simply did not have the physicality the part demands. Sandor needs to be a big guy, powerful and threatening, someone who looks like he could break you in half. Rory is all of that and more.
Mostly, though, it was his readings. We had other good ones, yes, but none to touch his.
One of the scenes in the side was Sandor's scene with Sansa, where he tells her how his face came to be scarred. In the space of a few lines, Rory had me terrified (where he roars, "Look at me," and makes her look at his face), made me chuckle (when he says no, the burns weren't dragonflame), and brought a tear to my eye (when he tells his story). After I saw that, I knew he was Sandor... and David, Dan, and Tom all agreed.
I think you'll going to love him as the Hound.
Of course, if we go to series, now we're going to have to find someone a foot and a half taller to play his brother. Now THAT will be difficult!"
A mí me parece una gran elección, por lo que cuenta Martin va a ser capaz de transmitir la esencia del Perro, y además mide 1,98.
