Fången på Karlstens fästning

This is not one of my favourite af Klercker films. A tale of secret documets (a new explosive invented) and a not very masterly master-ciminal who is after the plans - a typical "McGuffin" of the period. It is very typical of a kind of film that was becoming increasingly popular especially in north Europe (Germany and the Netherlands) and, in its slightly later form, would have an enormous influence on the young Hitchcock. But This one is a confused and rather pointless story. However, as always with af Klercker worth watchinf for the mise en scène (albeit less good than normal) and the splendid locations (this time a fortress on a mountainous island in Kungälv (a region where he also filmed I minnenas band in the same year) which makes for a thrilling finale.
