We've seen plenty of film makers shooting movies on an Apple iPhone in the past. However, director Steven Soderbergh—whose filmography includes movies such as Erin Brockovich, Traffic, and Ocean’s Eleven—is arguably the highest-profile iPhone movie makers yet.

His latest project, the psychological horror-thriller Unsane, was shot entirely on the iPhone, and Soderbergh wasn't afraid to admit (and embrace) that fact when speaking to IndieWire.

“I think this is the future,” Soderbergh said. “Anybody going to see this movie who has no idea of the backstory to the production will have no idea this was shot on the phone. That’s not part of the conceit."

In fact, the director was so impressed by the iPhone's movie capabilities and the recorded levels of detail, that he is likely to also use the Apple smartphone for future projects. “People forget, this is a 4k capture. I’ve seen it 40 feet tall. It looks like velvet," he told IndieWire. "This is a gamechanger to me.”

We don't know which exact iPhone model(s) Soderbergh used in the production of the movie, but it's fair to speculate that the latest iPhone X/iPhone 8 generation was deployed in combination with all sorts of professional lighting, audio and stabilization equipment.

By the way, in case you're curious, the movie's synopsis is the following:

A young woman is involuntarily committed to a mental institution where she is confronted by her greatest fear – but is it real or is it a product of her delusion?
