Christopher Nolan Reveals He Doesn't Own a Smartphone

Christopher Nolan, a famous movie director, said he doesn't have a smartphone.

He uses a simple flip phone instead.

He thinks if he had a smartphone, he would use it too much and it would take away time he likes to spend thinking.

On his movie sets, he doesn't allow phones because he wants everyone to focus.

Some actors like this rule because it helps them stay in the moment.

Nolan also doesn't like actors wearing Uggs on set because he thinks they make it hard to act realistically.
