The sfx-artist, Per Ingvar Tomren was living in the directors unfinished house months before, and during the filming.
Since the house wash't finished he used the living room as his studio, and it looked like a scene from one of Dexter's kill-rooms.
The director, Severin Eskeland was sleeping in the apartment during the whole shoot.
The guy who plays Policeman 2 owns the apartment, but he stayed with his girlfriend.
After misunderstandings in the casting, Jimmi Salomonsen who also is one of the producers on the film had to be cast as Policeman 2 the day before his first scene.
