The first thing Doug Cockle tells me about voicing Geralt of Rivia is that it once made him pass out.
Recording the grunts, impacts, and injuries of swordplay requires throwing the full breath of physical effort into a body standing still at a microphone. "You're putting all the breath effort in, but none of the physical action," he says. During one session, it caught up with him. "I didn't quite hit the floor. I lost my legs and caught a chair next to me." He had to pause and control his breathing before continuing.
