inmates; this was constructed by the production crew. Director Rod Lurie insisted on having the prisoners' cells face each other, but this is not the case at the Tennessee State Prison. To solve the problem, production designer Kirk Petruccelli created cells in a warehouse near the prison. Cinematography To show the balance of power, the film crew used multiple cinematography techniques involving different displays of color, lighting, camera and costumes. In the warden's office intense color was used to reflect freedom or power, in contrast to the washed-out colors from the less powerful yard. The contrasts shift as the story progresses, showing the increasing power of the prisoners. The American flag in the yard is described by Petruccelli as "the heart of The Castle" and is the only exemption to the washed-out color palette. Cinematographer Shelly Johnson, in collaboration with director Lurie and the design team, also used lighting and camerawork to signify the shifting of powers. For example, the yard is at first naturally lit and more influenced by daylight, in contrast to Winter's office, which is artificially illuminated by lamps. As the film progresses, the office is more fully infiltrated by exterior light through a broken window. The shift of power is also emphasized through camera techniques. Hand-held cameras were used when filming in the yard to make the audience feel as if they were "participants in the action". However, a very precise, sterile camera composition was used in the warden's office. The prisoners' world gets more precise during the film, while the colonel's world is filmed more loosely. Costume designer Ha Nguyen also demonstrates this contrast in the clothing of the cast. The film starts with the prisoners having their clothing divided by ethnicity, with African Americans wearing different headwear, Latinos wearing vests and various arm accessories, and the White Americans in cut-off T-shirts. After the arrival of General Irwin, the prisoners start wearing more similar clothing in a "sharp military manner". The uniforms of the prisoners change from the usual chocolate brown color to light grey, because of its muddled look on film and excessive darkness in some scenes. Ha Nguyen also contrasted the non-battlefield ribbons found on Colonel Winter's uniform with the battlefield medals found on General Irwin's uniform (seen only in the opening scene as Irwin is inducted into the prison). The wall created by the prisoners in the middle of the yard also
