Population Zero is a 2016 found footage crime thriller film directed by Adam Levins that premiered at the Newport Beach International Film Festival on April 26, 2016.The filmmakers were inspired to make the film after learning of the existence of a small portion of Yellowstone National Park that, under the Sixth Amendment's Vicinage Clause, could enable one to commit a crime without having a jury be able to try them, thus creating "the perfect crime". This idea was first written about in a Georgetown Law Journal article, "The Perfect Crime," by Michigan State University law professor Brian C. Kalt, and first dramatized in the 2007 novel "Free Fire" by C. J. Box, from which Population Zero borrows heavily.
