“Out here, it’s all about our hustle – and that’s it.” Here’s the decidedly NSFW redband trailer for the first feature film shot entirely on iPhone. Magnolia Pictures picked up Tangerine at Sundance, where the gritty pic had its world premiere in the Next section. The Mark and Jay Duplass produced the film from director Sean Baker (Starlet), who co-wrote it with Chris Bergoch. It stars newcomers Kitana Kiki Rodriguez and Mya Taylor.

It’s Christmas Eve in Hollywood, and working girl Sin-Dee (Rodriguez) is back on the street after a month in jail. Upon hearing that her pimp boyfriend (James Ransone) hasn’t been faithful during her lockup, she and best friend Alexandra (Taylor) set out to find him and figure out what happened. Their journey leads them through myriad L.A. subcultures, including an Armenian family dealing with their own repercussions of infidelity. Magnolia opens the film July 10 in select theaters.
