where was havoc filmed

The 2025 film Havoc was primarily filmed in Wales, despite being set in an unnamed city in the United States. Most of the movie was shot in a studio in Cardiff, Wales, with specially constructed sets, including three fishing shacks built for key fight scenes. Exterior scenes were filmed in various Welsh locations such as the countryside of Merthyr Mawr, Baglan near Port Talbot (notably the train tracks for the climax), and urban areas including Cardiff, Swansea, and Barry. Specific locations used to represent the fictional American city include Brangwyn Hall in Swansea (as a police precinct), Swansea University's Bay Campus, Trade Street in Cardiff (for Chinatown and market scenes), and Dragon Studios in Bridgend. The production involved extensive set dressing and visual effects to recreate an American city atmosphere while leveraging the architectural elements found in southern Wales
