David France wanted to put a real human face on the story, so conventional techniques of disguising one's appearance, such as blurring their faces, filming them in darkness or hiring actors to stage re-enactments were not enough. Eventually he opted for advanced facial replacement techniques using artificial intelligence and novel visual effects technology, so the viewer could see real faces displaying real emotions, while still protecting the identities of the speakers. The approach is a "game changer in identity protection," according to Documentary Magazine, and a brand new tool for documentary filmmakers.
