the thing i like about val lewton's horror films, is that he doesn't need to show a lot in the way of actual horror in order to produce an effective film. he uses the powers of suggestion very well, just as he does in "isle of the dead."
when a small of group of people are stranded on a deserted island owing to a deadly plague that is sweeping across parts of europe, the inhabitants of the island soon realise that they have the more serious problem of a possible vampire to deal with. one by one, the people succumb to the disease that the vampire is spreading but who is responsible?
leading the way in the fight for survival is greek army officer boris karloff who tries to maintain a kind of martial law. the director has cleverly used a lot in the way of unusual camera angles and dark lighting in order to achieve a moody and unsettling atmosphere.
this is one of the best horror films from val lewton and from "R.K.O" studios.
