The red-band trailer has dropped for one of Sundance’s most talked-about features.

It’s called Tangerine, and it’s about two transgender women in Hollywood. It was also shot with an iPhone 5s.

Of course, it wasn’t just an iPhone. The iPhone was the only device filming, but filmmakers needed a handful of extras. According to The Verge, those included an app called Filmic Pro, a set of anamorphic adapter lenses, and a steadicam.

You’ve seen YouTube videos. You know why the steadicam was necessary.

Without further ado, here’s the trailer:

Here’s the film’s official description:

It’s Christmas Eve in Tinseltown and Sin-Dee (newcomer Kitana Kiki Rodriguez) is back on the block. Upon hearing that her pimp boyfriend (James Ransone, STARLET, “Generation Kill”) hasn’t been faithful during the 28 days she was locked up, the working girl and her best friend, Alexandra (newcomer Mya Taylor), embark on a mission to get to the bottom of the scandalous rumor. Their rip-roaring odyssey leads them through various subcultures of Los Angeles, including an Armenian family dealing with their own repercussions of infidelity. Director Sean Baker’s prior films (STARLET, PRINCE OF BROADWAY) brought rich texture and intimate detail to worlds seldom seen on film. TANGERINE follows suit, bursting off the screen with energy and style. A decidedly modern Christmas tale told on the streets of L.A., TANGERINE defies expectation at every turn.

The film generated a lot of buzz and has since received some pretty good reviews. Vulture calls it “the trans revenge movie you’ve been waiting for” and the New York Times called it a “perfectly cast, beautifully directed movie.”

It’s due out on July 10.
