David Nykl: (On the difference between Zelenka and himself)That's an interesting question. It's obvious that there's a link because it's the same person, right? You are using characteristics that are your own. But you're obviously playing a character. So you're leaning on things that you don't necessarily, maybe, do in real life. Radek Zelenka's a scientist. He's much more careful. He tends to worry about things more than I do, tends to be much more precise about things than I do. The distinction is character-based. He's much more of a scientific mind than I think I would consider myself to be. By scientific mind, I mean the scientific approach to things. The precision, the care, the attention to detail, that sort of thing.
