The 2025 TV series "Code of Silence" is primarily set in Canterbury, Kent, England, but most of the filming took place in other locations such as St Albans and Watford in Hertfordshire. Specific sites for filming include the recently vacated Watford police station for police scenes, The Hub on the Verulam in St Albans as a café location, one75 bar in West Hampstead for nightclub scenes, and Wrotham Park for a fictional swanky hotel. Additional filming locations include Milton Keynes and the BRE Science Park. Some archive footage was also shot in Canterbury itself. In contrast, the 1985 film "Code of Silence" was filmed in Chicago, Illinois, with scenes shot at various sites including Lower Wacker Drive, Chicago River, Graceland Cemetery, River Forest, and other Chicago landmarks. Thus, the filming locations differ greatly depending on the specific "Code of Silence" work referenced—the 2025 TV drama was mainly filmed around Hertfordshire and London areas while the 1985 movie was filmed in Chicago.
