I agree. The interviewer is clearly frazzled, taken aback, has a very difficult time figuring out what to even ask.
Having said that, why is the lighting/video SOOOO bad? [That was what I meant by the picture being awful upthread, not the picture DL posted]. I don't like that we can't see half of Kubrick's face.
As far as the lighting, my feeling about that is that this interview was done in quasi-secret, and so perhaps at Kubrick's home or the interviewer's home, and so they would have avoided wanting to have a large or even professional camera crew. Kubrick wanted it to be hush-hush, and it may even have been a spur of the moment thing. If at his home, perhaps he didn't want nosey neighbors seeing someone come in with a camera (and so told him to bring a small one he could tuck away in a coat), and didn't want his wife to know he was giving it either. It's hard to say, but it would be nice to get a little back-story from the interviewer. Reportedly he's tight-lipped about the entire thing and won't talk about it (this was released in 2015 if I recall). Perhaps he's under pressure from the powers that be.
I tried to watch it thinking if I wanted to stage something like that, script it, that it just seems so spontaneous, and Kubrick really seemed to be speaking off the cuff. He never gives away the game, by cracking a smile. Interviewer does seem legitimately taken aback by the answer, to the point of getting so excited that he's talking all over and cutting off Kubrick. That's certainly not how I would script a fake interview. But maybe these guys are REALLY good. And the expression on Kubrick's face did look as if he wanted to get something off his chest, and I sensed there was still a mixed motived, where part of it was that he wanted to get credit for this great achievement, and part of it where he felt a bit bad about the fraud. He says that when he was asked to do it, he didn't even think about the fraud part, but just about it as another "movie" project that he was flattered to have been asked to do ... never considered it from an ethical standpoint.
