A trailer has arrived for “I Am Another You,” Nanfu Wang’s award-winning follow-up to “Hooligan Sparrow.” The atmospheric spot clocks in at over two minutes but we don’t hear a single word from the doc’s main character, a drifter named Dylan. Instead, we see glimpses of how he spends his days — idyllic snippets of him chopping wood, fishing, and walking along the beach. But then things take a turn for the worse, and we’re not told why, but the police become a part of Dylan’s story.

Fortunately, the film’s official synopsis helps fill in the blanks a little. When Wang “first came to America, Florida seemed like an exotic frontier full of theme parks, prehistoric swamp creatures, and sunburned denizens. As she travels wide-eyed from one city to another, she eventually encounters [Dylan],” the description hints. “Fascinated by his rejection of society’s rules and unsure of his past, Nanfu follows Dylan with her camera on a journey that spans years, takes her across America, and explores the meaning of freedom. But as Nanfu delves deeper into Dylan’s world, she discovers something that calls her entire worldview into question.”

Wang’s first film, “Hooligan Sparrow,” follows women’s rights advocate Ye Haiyan, better known as Hooligan Sparrow, as she fights for human rights in China. She led a protest when two Chinese government officials received light sentences after sexually abusing six schoolgirls. The doc was filmed with hidden cameras, pocket recorders, and a camera built into a pair of glasses, and Wang smuggled the footage from China to prevent it from being seized. “Hooligan Sparrow” was shortlisted for Best Documentary Feature at this year’s Academy Awards.

“I Am Another You” made its world premiere at this year’s SXSW, where it won two awards: A Special Jury Award for Excellence in Documentary Storytelling and the SXSW LUNA Chicken & Egg Award. The film opens theatrically in NY on September 27.
