Inspired by the American police series, the script originally had several scenes where the main character Joel shoots a gun. Actor 凯·莱蒂宁 refused, since he wanted to ground the action in a realistic Finnish setting.
The Russian company "Rock Films", owned by CEO 阿列克谢·乌奇捷利, provided help for the location shooting in St. Petersburg. Based on the producer Erkki Kivi, production assistant Boris Sterin had a special permission for filming from Ministry of Internal Affairs of Russia. The crew was granted access to film in a real militsiya office, to stop the traffic for a few hours in front of the Grand Hotel Europe, to set a car chase with submachine guns on the streets of St. Petersburg, and crash a car through a window.
