The thing I focused on most was his voice. Why? The voice is what I look for first and foremost with just about every character I play. I don’t have an answer why. And Bruce was really accommodating and open and collaborative in helping me do that. He recorded himself reading some of my voice-over lines so that I could hear how he would sound saying them, which I thought was really cool. But mostly it was just hanging out with him, getting to know him, having dinner, talking about music or anything else was probably what was the most useful in trying to get a sense in what I was then going to portray.
