When the Sundance Film Festival took its name from the annual ceremony of the peoples of the Great Plains, there were concerns that the organizers were appropriating First Nation culture. But since 1993, the festival has made purposeful space for indigenous creatives, from the original Native American & Indigenous Program to the more recent Indigenous Film Tour, which returns with short films from cultures as diverse as the Houma people of Louisiana and the Buryats of Siberia, plus an archival throwback from Reservation Dogs co-creator Sterlin Harjo. – Richard Whittaker
