Christopher Nolan reveals why he'll never own an iPhone

Christopher Nolan has revealed why he still refuses to own a smartphone, admitting that his biggest fear is becoming "horribly addicted" if he ever switched to an iPhone.

The Oscar-winning filmmaker opened up about his technology habits during an appearance on The Tonight Show Starring Jimmy Fallon, where he confirmed that, despite directing some of Hollywood's biggest blockbusters, he still relies on a basic flip phone when necessary.

"I have a flip phone, like a dumb phone, I use when I travel and stuff," Nolan said. "That's kind of great." He acknowledged that many people find his decision surprising but insisted he has no plans to embrace smartphones.

Explaining his reasoning, the The Odyssey director said he worries an iPhone would consume too much of his attention.

"I would be horribly addicted," Nolan admitted. "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."

Fallon also asked how Nolan manages to oversee massive productions without constantly being connected. The director laughed off the question, explaining that he is surrounded by collaborators who keep him informed.

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

Nolan also confirmed the long-standing reports that mobile phones are prohibited on his film sets, a policy several of his actors have praised over the years. The Odyssey star Jon Bernthal recently described the phone-free environment as refreshing, comparing it to "church" because it allowed everyone to focus entirely on the work.

Phones aren't the only modern items Nolan keeps off set. He recently explained that he discourages actors from wearing Ugg boots during filming because they serve as a "signifier of modernity" and can momentarily break the immersive atmosphere he tries to create for performers.

Nolan has long favoured an old-school approach to filmmaking, avoiding email, texting and smartphones while embracing practical effects and focused, distraction-free sets. His latest comments offer another glimpse into the unconventional methods that have become synonymous with one of Hollywood's most celebrated directors.
