Christopher Nolan explains how he stays informed despite not having a smartphone:

“I actually do read the newspaper every day. Yes, the physical newspaper. No, I go online plenty, probably more than I would like. But I do it at a computer in my office. You know, I don’t like to be distracted during the day overly. So I don’t carry a smartphone with me and all the rest. But I know I stay very informed as much as I can, you know, through traditional media, through online as well. But I don’t do any social media or anything like that. I try not to get too bogged down in the process of feeling connected with the world. It doesn’t really take long to, you know, get up to speed on the news of the day. You don’t need to spend your entire existence doing it. And I’m very easily distractible, so it’s better for me to put that in a box and have a particular period of time where I’m paying attention to what’s going on outside world. And then I need to focus on the thing it is that I’m doing. And so when I’m making a film, I very much get into a bubble and don’t keep in touch with what’s going on in the world. But that’s sort of the job, really. I mean, I’m being paid or being entrusted with a budget. And I’m being given the responsibility of focusing entirely on this particular film while I’m making it. That’s my job.”
