Ok. But what are you saying? I mean, what do you think he's thinking about?
I have no idea. But he's not really listening to the dude on the phone, with the majority of his attention. He's remembering something else someone said.
He's also repeatedly looking over Ridley's shoulder at something. (That could be just something interesting, of course.)
He doesn't like making eye contact and looks at the ground a lot. This could just be a cell phone thing, but most people actually keep their head tilted straight ahead or slightly upward.
He keeps staring at a little notepad. Notes? He had the phone number on it, but it didn't look like a script or anything.
Of course, he could just be nervous around a camera.
All I'm really saying is that his body movement seems off, for whatever reason. It looked like he was gonna start in on the peepee dance at any moment.
