Was a commercial failure in Sweden due to not being able to find Swedish distributors. The biggest distributor in Sweden did not want to give it a big release and did not give it much promotion thinking it was too low quality. Ironically it was by far the most popular Swedish movie in international markets that year.
Paramount bought the rights to the Swedish home video market after watching only 20 minutes of the film.
During the filming the cast and crew where plagued by the extreme cold, with temperatures falling below 30 Celsius zero. During many scenes, the cameras broke down because of the cold and had to be warmed up. During her final fight scene 'Grete Havensköld' lost all feeling in her feet. She eventually started to cry and a sound tech had to take her into a van and warm her feet in his armpits. In another scene when Jonas Karlström was hanging in a lamppost covered in fake blood, it started to rain, despite being far below zero. The rain then froze on all the equipment and clothes, creating a layer of ice on everything. 'Anders Banke' referred to it like napalm, but with ice. During the final showdown with the cops and the vampires it also started to rain, creating the same problem.
