The shooting of the film began in the spring of 2004. The outdoor scenes were shot at the 8.5 hectare Cinevillabacklot in Tukums, Latvia, where parts of Riga's Old Town and Riga's Pārdaugava district were built especially for Defenders of Riga. Around 200 extras took part in the film's battle scenes.[3] It was the first Latvian film to make an extensive use of special effects and computer graphics.[2]
