Christopher Nolan reveals why he refuses to switch to an iPhone

Christopher Nolan confessed why he continues to avoid smartphones, saying he prefers using a simple flip phone because he fears an iPhone would distract him from the quiet moments that fuel his creativity.

The Oscar-winning director also confirmed that he still enforces a no-phone policy on his film sets.

Nolan says a smartphone would distract him

Appearing on The Tonight Show Starring Jimmy Fallon, Nolan admitted it may seem unusual that he does not own a smartphone.

"I have a flip phone — like a dumb phone — I use when I travel and stuff. That's kind of great."

The The Odyssey director explained that he deliberately avoids iPhones because he worries about becoming dependent on them.

"I would lose those pockets of time that I really value where you're just thinking. Just sort of looking out the window and thinking about what your next film might be."

Director relies on his team instead

When Fallon asked how he manages large-scale productions without a smartphone, Nolan said he is constantly surrounded by people who keep him informed.

"I am surrounded by people helping me all the time. It would actually be pretty hard for me to get away from the information that people are trying to give me."

He also confirmed the long-standing reports that mobile phones are not allowed on his film sets.

Actor Jon Bernthal, who appears in The Odyssey, previously said the policy gave him a welcome break from his phone, with his wife encouraging him to embrace the experience.

Why Ugg boots are also discouraged

Nolan also addressed another well-known rule on his sets — his dislike of Ugg boots.

He explained that oversized slippers can pull him out of the world being created on screen, even though he acknowledged the reasoning sounds unusual.

"There are just certain things that remind you you're in the real world as opposed to the world we're trying to create for the actors."

According to Nolan, keeping distractions to a minimum helps both the cast and crew remain immersed in each scene while filming.
