Yo-Yo Ma, Pawo Choyning Dorji on ‘A Song for the Snow Lion’ as Trailer Unveiled Ahead of Telluride Bow (EXCLUSIVE)

The Telluride Film Festival is set to premiere "A Song for the Snow Lion," a 21-minute short film that unites the legendary cellist Yo-Yo Ma with Bhutanese director Pawo Choyning Dorji. The project, rooted in a Himalayan folktale about disappearing glaciers, has just had its first trailer unveiled by Variety. This marks a significant collaboration between two artists from vastly different worlds, brought together by a shared concern for the planet's rapidly changing climate.

The film's origins trace back to a direct request from Ma, who had long harbored a desire to visit the remote Himalayan kingdom. "I have always wanted to go to Bhutan, to meet its people, hear their stories, see the glaciers, and witness how they feed the mighty rivers that course through some of the most populous countries in the world," Ma explains. Initially, he proposed a straightforward music video addressing global warming, but Dorji, whose 2019 film "Lunana: A Yak in the Classroom" secured Bhutan's first-ever Oscar nomination for best international feature, suggested a more narrative-driven approach. Dorji instead wanted to adapt a folktale from his childhood, wherein snow lions—mythical guardians of the mountains—are believed to inhabit only places where glaciers still thrive. "A Bhutanese child does not learn to protect the mountain by being shown a chart," Dorji says. "She learns it because she is told a snow lion lives up there."

Dorji's previous work, including the political satire "The Monk and the Gun" (which was shortlisted for an Oscar but didn't make the final cut), has consistently explored the tensions of Bhutan's opening to the outside world. This new short continues that thematic thread, asking what is lost in the name of progress. "It's the same question I am returning to, of what we stand to lose, except this time the answer isn't in our hands," Dorji notes. "Our glaciers are melting away regardless of what we choose." The director, who has gained international recognition for his distinct visual storytelling, sees the snow lion as a symbol of the awakened mind, a concept he says he only fully grasped after repeated visits to the Lunana Valley. For him, the glacier represents purity of action, and its retreat signifies a profound spiritual and ecological loss. As the film's young protagonist suggests, to tell a story in Bhutan is to untie a knot—an act of liberation that Dorji believes is central to his filmmaking.

Production for "A Song for the Snow Lion" was an arduous undertaking, with the crew trekking 14 days from the nearest road to reach Lunana, a valley situated at elevations above 5,500 meters (18,100 feet). The entire operation was powered by solar batteries, a logistical challenge that Dorji felt was integral to the project's spirit. "In Bhutan, the hardship of reaching a sacred place is part of what makes the offering an offering," he explains. "You do not receive the blessing of a mountain by arriving comfortably." Ma, who suffered from altitude sickness during the shoot, still managed to perform the film's climactic cello piece alongside Bhutanese folk singer Kelden Lhamo. He described the experience as life-altering, particularly the moment when, just after filming wrapped on that scene, a glacier calved in the distance, collapsing into the water below—a sound the team captured and incorporated into the film's finale. "We had gone up there to make an offering to something we were told lives in the ice," Dorji says. "The ice answered." The film also features 10-year-old Kinley Karma Lhazing, a young yak-herder from Lunana.

Beyond its environmental message, Ma views the film's central metaphor as a reflection on human interconnectedness. "Thinking about water helps me understand that we are not separate from the earth and that our survival and the health of the planet are one," he says. "Like music, water travels lightly, it knows no borders." He draws a direct line to recent catastrophic flooding in Nepal, calling it a stark reminder of the stakes involved. Dorji, for his part, hopes the film's impact is simple and profound: "If the film leads even one person to care a little more about the earth we live on, then I will be a content and happy filmmaker."
