This is something that might be overlooked technically — every time Justin is on the right side of frame, Mark’s on the left side of frame, and halfway through the scene Justin moves to the left side of frame, and Mark moves to the right side of frame. This was heavily orchestrated when we were on set. This is not something that’s by accident, or something that just happened because the actors wanted to move individually. This is an orchestrated scene. Watch, so Justin moves to the left side of frame — cuts back, and Mark is over there. This is… [laughs] just so wonderful, I mean, you almost feel like how could anybody else be making movies if they’re not thinking about stuff like this? He moves back, I move back. It’s — it’s just incredible, when I was on set I had no idea of the millions of things that were happening around me that were making this movie, I just happened to overhear that this was what they were doing. I happened to overhear it. If I didn’t overhear it, I never would have known, and I’d watch the movie a hundred times and wouldn’t pick up on it because I just don’t… pick up on things like that.
