Yellow Bird, the Swedish production company behind the Millennium trilogy, has secured rights to six books in Liza Marklund’s Annika Bengtzon series.

Marklund’s novels, which have been translated into 30 languages, follow the adventures of crime reporter Bengtzon, who is dedicated to her investigative work. There are eight books in the series but Yellow Bird has only bought Studio Sex,Prime Time, The Red Wolf (Den Röda Vargen), Lifetime (Livstid) and A Place In The Sun (En Plats I Solen) so far.

Yellow Bird producer Jenny Gilbertsson says the films will each have a budget of $2.3m (SEK16.6m) and will be shot back to back. It is not clear which title will be produced first.

The acquisition comes ahead of the release of the second instalment of the Millennium trilogy, The Girl Who Played With Fire, which opens on September 18. The Girl With The Dragon Tattoo (also know as Men Who Hate Women) has been a global phenomenon this year, scoring more than 6 million admissions worldwide and taking $72.8m (€50m) to date.
