 Many of the films prison scenes were filmed at the old Hamilton  County Jail in Cincinnati, Ohio. The Jail, also known as the  "Cincinnati Workhouse", had been permanently closed prior to the  location filming of the movie. It had been built during the Civil  War to house enemy troops and was still in use by Hamilton county  and Cincinnati area police agencies as a jail as late as the 1970s.  It was closed due to being "inhumane, cruel and unusual" by modern  jail standards.
