Video - Tangerine, one of the best films at Sundance, was shot with an iPhone 5S

The story of two trans sex workers in Hollywood, California

"Tangerine" by director Sean Baker (who wrote the film with Chris Bergoch,) was one of the best films at this year's Sundance Film Festival, and due to budget constraints was entirely shot using an iPhone 5S. Well, three of them. And an $8 app called "Filmic Pro", that allowed the filmmakers fine-grained control over the focus, aperture, and color temperature. All right, you'll also have to add to the budget a hand-held support used to stabilize shots (a "Smoothee".) And a set of anamorphic adapter lenses that attach to the iPhone. Baker also used "Final Cut Pro" and "Da Vinci Resolve" for editing. And that's pretty much it. Apart from the (surprising) technicalities, the movie is... surprisingly good. Ok, it's totally awesome. And beautifully directed, colorful and saturated (the title was inspired by orange emerging as the dominant color in the film.) The review aggregator website Rotten Tomatoes reports a 95% approval rating, and an average rating of 7.8/10 based on 81 reviews. "Tangerine" is the story of trans woman sex worker Sin-Dee Rella (Kitana Kiki Rodriguez), who has just finished - just on Christmas Eve - a twenty-eight day prison sentence, and her best friend Alexandra (Mya Taylor), also a trans sex worker in Hollywood, California. And if you live in the UK, Tangerine will be released in the United Kingdom... tomorrow!
