Gracie is only one part of the documentary — Huntsman and a Chinese dissident round out the storyline — but the girl's return to China in 2009 with her family and a hero's welcome at her one-time orphanage offer a powerful side note to the impact of U.S. policy on Beijing and its policies toward America.
The teenager, abandoned as an infant in a vegetable market and adopted at 6 months of age by one of the more affluent American families, speaks little Chinese herself, something she says in the documentary that embarrasses her when people assume she's fluent.
But she's proud of the role she gets to play: a Chinese-born American brought on the world stage as a girl who has the ability to do what her counterparts in her home country can't.
"I'm free to speak the truth," Gracie says, nearly breaking down behind a microphone where she helps narrate "All Eyes and Ears," a documentary years in the making by director Vanessa Hope and co-produced by Geralyn White Dreyfous, head of the Utah Film Center.
One can document the challenging relationship between the two countries through high-profile incidents or, as Hope does with this film, tell the story with individuals in key roles to shape the future of the connection.
Huntsman, who had returned Thursday from a visit to Beijing, said he wasn't sure how the film would turn out, but he praised Hope after its screening.
"She kind of weaved everything together in a way that illustrates the complex nature of the relationship," Huntsman told the crowd during a question-and-answer session.
Much of the filming took place before Huntsman left his ambassador post in 2011. News of the film brought some criticism during his short-run bid for the presidency, but the documentary turned out less about Huntsman and his work as a diplomat than about his daughter's intriguing role.
In the movie, he said that his goal, like that of his predecessors, was to leave China better than he found it.
"Everyone wants this relationship to work," he said. "It's too important to the world."
One of the more emotional parts of the film follows Gracie's return to Yangzhou, where she was born. The former orphan was greeted with drums, fireworks and giant banners. "Welcome back home" they say in English and Mandarin. She walks a red carpet, plants a tree and is surrounded by young girls who want a hug.
Video of wooden cribs and infants comes next and Gracie's mood shifts.
"I worry about all the ones who didn't get adopted like I did," she says. "What happens to them? This feels like 'The Hunger Games.' It's my favorite book."
Gracie is shy, but she often accompanies her father on trips as shown in the film. Huntsman considers her both Chinese and American, noting that she would make a great future U.S. ambassador but that Gracie would rather be an artist, cure cancer (as has become the life's mission of her grandfather, Jon Huntsman Sr.) or befriend pandas.
