“Gul'dan thinks magic is what they need to insure the survival of their species,” Wu says. “He has to take souls — humans, other animals — and feeds off them. That’s his fuel. Even though it’s corrupting and makes (the orcs) turn into huge monsters, he thinks that’s the only way to go.”
This behind-the-scenes video shows Wu in his mo-cap outfit getting Gul’dan’s movements right, plus his admission of having a special relationship with Warcraft: His wife plays the video game, and even though he was supposed to be taking a year off after their baby daughter was born in 2013, Wu recalls, because it was Warcraft “she gave me permission to audition.”
