The story takes place in the city of Frankfurt, but most of the scenes where shot in the area of Stuttgart. Only one third of the film was actually shot in Frankfurt.
Almost the complete showdown was shot in one single night with three units filming simultaneously. Two fight scenes, one shootout and a big explosion were shot that night. This was only possible, because the shoot took place at one big industry complex and because director Martin Schreier rushed from set to set during takes.
