Julian Kwasneski was the voice director on The Walking Dead Video Game by Telltale Games. Both. I watched the show to hear how the Walking Dead universe sounded, how people conversed, accents, styles, general vibe, music, etc. Since the games were being based on the comics I also read all of them. I found the comics to be a great source for reference because they allowed my imagination to wander and left me with a good impression of the drama and horror of the world. You'd have to ask the master this one, Jared Emerson-Johnson did all of that. More than you could ever imagine.
