I know it's not really cheap but the best price i've seen for this since its release.
Swedish thriller based on the bestseller by Stieg Larsson. In 1966, 16-year old Harriet Vanger (Ewa Froling) disappeared without a trace from a family gathering on the island owned by the powerful Vanger family. Nearly 40 years later, disgraced magazine journalist Mikael Blomqvist (Michael Nyqvist) is contacted by Harriet's uncle, powerful industrialist Henrik Vanger (Sven-Bertil Taube), who asks him to write the history of the Vanger family and find out what happened to Harriet. Joining forces with troubled young computer hacker Lisbeth Salander (Noomi Rapace), Mikael starts to delve into the past of the Vanger family - and unearths a history more sinister and violent than he could ever have imagined.
