<span>If there's a sense that Steven Soderbergh has come full circle with his latest film, </span><span><em>Unsane</em></span><span>, it's understandable. This psychological thriller cost </span><span>US$1.2 million – </span><span>the budget of </span><span><em>sex, lies and videotape</em></span><span>, he says</span><span>. Now nearing its 30</span><span>th anniversary, Soderbergh's Dh4.4m 1989 debut </span><span>was a sensation at Sundance, won him the Palme d'Or in Cannes and launched the unknown into the stratosphere.</span> <span>Since then, he has won a Best Director Oscar for </span><span><em>Traffic</em></span><span>, directed the all-star </span><span><em>Ocean's</em></span><span> caper trilogy and, most recently, enjoyed a four-year hiatus </span><span>from filmmaking to take up painting. With all that in mind, some filmmakers might consider it a failure if, after three decades, they're back making a movie for the same price that their </span><span>debut cost. But the 55-year-old Louisiana native works differently to most.</span> <span>Set in a mental asylum and starring </span><span><em>The Crown</em></span><span>'s Claire Foy, </span><span><em>Unsane</em></span><span> was shot on a regular iPhone 7 Plus. With its in-built 4K camera, it's a pocket-sized device capable of producing big-screen images. "It was really exciting," Soderbergh says</span><span>. "The positive aspects of it far outweighed for me the few things that you can't do. Or that you probably could do if you took more time, but I didn't have a lot of time."</span> <span>He's not the first to try this – Sean Baker's 2015 film </span><span><em>Tangerine </em></span><span>used the iPhone 5 to tell a fizzy tale of Los Angeles street hustlers – but Soderbergh's work will certainly give encouragement to others. In an age when movies are becoming increasingly expensive, making it difficult for first-time filmmakers to get their start, Soderbergh has found the perfect way to shrink the economics of a </span><span>production.</span> <span>“There’s certainly an impact in the speed [of a film shoot]. You can do more work in a certain amount of time,” he says. Personnel are also reduced. “We had a really, really small crew. The camera department was the assistant cameraman and the camera package fit – all of it – in a backpack. So there’s a very tangible effect when you’re travelling that light, in terms of doing things and moving from this location to that location.”</span> <span>It's typical of his desire </span><span>for experimentation with the business models of filmmaking. His 2005 movie <em>Bubble</em></span><span> infuriated many in the industry when it was released simultaneously in theatres, on DVD and cable, something that's now quite </span><span>common.</span> <span>"If something is possible, you know somebody is going to do it," he says</span><span>. "And so I guess my attitude then was, 'This is going to happen. It's possible. So why don't we start this process of exploration?'" Of course, </span><span><em>Unsane </em></span><span>wouldn't work half as well without an electric script from Jonathan Bernstein and James Greer. </span> <span>The project started after Greer contacted Soderbergh, who asked him to write a </span><span>horror. The two had worked </span><span>on two unrealised projects – a Cleopatra musical (for Catherine Zeta-Jones) and an adaptation of John Barth's novel, </span><span><em>The Sot-Weed Factor</em></span><span>.</span> <span>"We've spent enough time in a room talking that Jim knows what kind of movie that I'm going to respond to," says Soderbergh. "If he shows up with something that's really violent and has a lot of questionable, gratuitous activity in it, I'm probably not going to respond. I think he was smart enough to know the more this is like </span><span><em>Repulsion</em></span><span>, the better the shot that I'm going to respond."</span> <span>Certainly, Roman Polanski's 1965 psychological horror, which starred Catherine Deneuve as a woman on the verge of a nervous breakdown, factors into </span><span><em>Unsane</em></span><span>. Foy plays Sawyer Valentini, a bank worker who escapes to Boston after a wretched time with a stalker (Joshua Leonard) on her case. But after a therapy session goes awry, she unwittingly commits herself to a 24-hour stay in a psych ward, leading her into a Kafka-esque</span><span> nightmare.</span> <span>Soderbergh spent the first half of 2017 working his way through a long list of asylum movies, like </span><span><em>One Flew over the Cuckoo's Nest</em></span><span> and </span><span><em>Shock Corridor</em></span><span>, in search of inspiration. "I'm looking at things to try and figure out what I want to steal</span><span>," he says with a grin. But there nobody could accuse him of plagiarism: </span><span><em>Unsane</em></span><span> feels </span><span>fresh. Like much of his finest work – his madcap linguistic comedy </span><span><em>Schizopolis</em></span><span>, his non-linear crime film </span><span><em>The Limey</em></span><span> – Soderbergh's at his best when he's breaking </span><span>the rules.</span> <span>With no phone-related glitches or breakdowns during the making of </span><span><em>Unsane</em></span><span>, it's been a success</span><span>. Soderbergh's </span><span>working on his second iPhone movie, </span><span><em>High Flying Bird</em></span><span>, starring André Holland, who starred in his TV hospital drama </span><span><em>The Knick</em></span><span>. But he's not expecting every director to abandon the large-scale apparatus that comes with most filmmaking. "Some people can't wrap their mind around doing a $20m film and shooting it on a phone that costs $700. That's a real obstacle." Obstacles? He thrives on them.</span> <span><em>Unsane opens on Thursday </em></span><span><em>across the country</em></span> ___________________ <strong>Read more:</strong> ___________________
