This is the third film in the 2005-2006 series - IMDb's follows/followed by order of this and Borkmann's Point (2005) is reversed, but somehow can't be corrected as they were released on the same day. Moreover, Borkmann's Point (2005) is actually the first film, followed by Carambole (2005) - those were released out of order as the latter premiered in theaters while the former was released straight to video, just like this.
Elisabet Carlsson who plays Irene Leverkuhn played lead character Henni in Kvinna med födelsemärke (2001).
