Many locations in and around Dallas were used in the production. An office in Renaissance Tower was used for the interior of OCP, and the exterior is the Dallas City Hall (modified with matte paintings to look taller). The OCP elevator was that of the Plaza of the Americas. The Detroit police station is a combination of Crozier Tech High School (exterior) and the Sons of Hermann hall (interior), and the city hall is the Dallas Municipal Building. Scenes of Boddicker's gang blowing up storefronts were filmed in the Deep Ellum neighborhood. One explosion was larger than anticipated; and actors can be seen moving out of the way, Smith having to remove his coat because it was on fire and the actors involved receiving an additional $400 stunt pay. The SHELL gas station that explodes was located in the Arts district, where locals unaware of the filming made calls to the fire department. The scene was scripted for flames to modify the sign to read "HELL"; Davison approved it but it does not appear in the film. Miner called it a disappointing omission.
