Today we welcome Sterlin Harjo back to StudioTulsa. The celebrated locally-based filmmaker has a new movie, which he tells us about. It's a documentary short called "Terlton," and it'll have its world premiere this coming Saturday, the 13th, as part of the 2019 Circle Cinema Film Festival . "Terlton" takes us back to the summer of 1985, when a small town in Oklahoma -- incredibly, and so sadly -- lost a full one-fourth of its population when an explosion happened at a local fireworks factory.
