Factual error: In the scene where Lewis dials the police at the gas station, he says "Rawlins County Sheriff's Department please." There is no such county in Wyoming (where this particular scene is) named Rawlins County. He should have said Carbon County. Also, Table Rock is in Sweetwater County, and there are no police services there. (00:36:50)
