My initial impression (before playing the analysis part):
I got the sense initially that John was uncomfortable and nervous. He had a bit of a stiff, guarded posture (I noticed his hands in front of his body, too) and a lot of tension in both his face and body, which was especially apparent when he looked down. When the interviewer brought up American Beauty, he became very confused (both on his face and through his voice) as he was not in that film and thus became both surprised and offended that the interviewer did not do her research on his work. He showed this through becoming even more uncomfortable by tensing up his posture, crossing his legs, touching his nose, and tensing up his mouth, and this tension increases as she asks him repeatedly if that was him.
After the analysis:
I totally neglected to see him checking her out in any way!
It was all very subtle and through very brief glances. I find it hard to get very brief stuff like that. I got all of the uncomfortable/tense/nervousness stuff down, but I thought it was because perhaps he hadn't done an interview in a while and was genuinely nervous about doing it. I noticed most of the contextual cues that he displayed though when he was asked about American Beauty (getting increasingly uncomfortable because of the interviewer not knowing he was in it and not being convinced that he wasn't).
