Julian Brave NoiseCat initially didn鈥檛 want 鈥淪ugarcane鈥� to be such a personal film.

The Indigenous filmmaker says he intended to remain behind the camera for the Sundance prize-winning documentary, which he co-directed with Toronto鈥檚 Emily Kassie.

The film is a quietly haunting account of deaths, rapes, suicides and missing children at the former St. Joseph鈥檚 Mission Residential School, a Catholic-run facility near Sugar Cane reserve in Williams Lake, B.C.

But NoiseCat quickly realized the film would be incomplete if he and his family weren鈥檛 part of it.

鈥淢y family had stories that cut to the core of the infanticide that happened at St. Joseph鈥檚 Mission,鈥� NoiseCat, a member of the Canim Lake Band in British Columbia, says on a recent video call from Martha鈥檚 Vineyard, where he was screening the film.

鈥淚 felt that if I wasn鈥檛 willing to go there with my own story and my own family鈥檚 story, then would I really be giving this documentary my all?鈥�

NoiseCat appears in the doc with his father Ed Archie NoiseCat, who was born at St. Joseph鈥檚 Mission. The film explores long-standing allegations that priests who fathered children with school residents sent the infants to an incinerator.

鈥淪ugarcane,鈥� which won the directing prize at this year鈥檚 Sundance Film Festival, explores the horrors at St. Joseph鈥檚 and its ripple effects, while putting human faces to the tragic legacy of Canada鈥檚 residential school system, featuring testimonials from survivors.

NoiseCat traces the film鈥檚 genesis to 2021 when the Tkemlups te Secwepemc First Nation said about 200 possible unmarked burial sites had been found around the former Kamloops Indian Residential School in British Columbia. Kassie, who used to work with NoiseCat at The Huffington Post, reached out to her former colleague about collaborating on a documentary about the discovery.

鈥淚 was born and raised in Canada but I had never turned my lens on my own country and the atrocities committed against its First Peoples,鈥� says Kassie, an Emmy and Peabody-nominated investigative journalist and filmmaker.

Kassie called NoiseCat to tell him she had connected with the Williams Lake First Nation, which was leading an investigation into the grounds of the former St. Joseph鈥檚 Mission, which operated from 1886 to 1981.

鈥淭here was a long pause on my end of the line, and then I said, 鈥榃ow, that鈥檚 really crazy. Did you know that that鈥檚 the school that my family was taken away to and where my father鈥檚 life began?鈥� recounts NoiseCat.

鈥淥ut of 139 residential schools across Canada, Emily happened to choose the one school that my family was sent to.鈥�

The film follows two people involved with the investigation 鈥� Charlene Belleau and Whitney Spearing 鈥� as they collect testimonies from survivors about their experiences at St. Joseph鈥檚.

鈥淪ugarcane鈥� also explores the relationship between NoiseCat and his father, who left Williams Lake and his family.

鈥淢y father had for his entire life lingering questions about the circumstances of his birth and what happened immediately before and after,鈥� says the 31-year-old NoiseCat.

鈥淔inally getting some knowledge and understanding of what happened to him and his birth, and then some understanding between him and I of how that impacted both of our lives, was a really important step to finding some healing and peace. I think that story in microcosm is the story of First Nations families all across Canada and beyond.鈥�

NoiseCat and Kassie say that despite its tough subject matter, 鈥淪ugarcane鈥� includes humorous and heartwarming moments: NoiseCat and his father embarking on a road trip and smoking marijuana together, survivors enjoying themselves at powwows.

鈥淎 lot of this is about survival against all odds and about people rising up against extraordinary horror and hurdles,鈥� says Kassie.

鈥淲hat鈥檚 so remarkable about this community is it鈥檚 filled with beauty and life and family, even though that鈥檚 exactly what the residential school system was trying to eliminate.鈥�

NoiseCat says the film has received more attention 鈥� from interview requests to film festival pickups 鈥� in the United States and abroad than in Canada.

鈥淚 think it鈥檚 a real shame that the Canadian government, as well as elements of the Canadian media and public, have gotten tired of hearing about residential schools,鈥� says NoiseCat.

鈥淭his is a reality that First Nations people all across the country and beyond are still grappling with every day, and it鈥檚 a matter of life or death.鈥�

鈥淪ugarcane鈥� hits select theatres Friday.
