In this brilliantly scripted story, a policeman investigates the murder of an aboriginal girl whilst coming up against the reluctance of his colleagues to help, the indifference of the local population, and some very unpleasant discoveries.

Mindhunters

2004

L.A. Confidential

1997

With its clever plot set in sunny 1950s-era Los Angeles, and starring the wonderful Kim Basinger and the charming Russell Crowe, L.A. Confidential is a brilliant, atmospheric film. Two fearless police officers investigating a series of murders uncover the criminal secrets of the legendary American city. Unmissable.

Män som hatar kvinnor

2009

This earlier, Swedish-language version of the The Girl with the Dragon Tattoo is not so slick as the American version. This is essentially a film about ordinary people who sometimes end up living side-by-side with scoundrels. Although there are several plot lines, they merge together beautifully into a satisfying whole, with each one forming a key component.
