The similar theme music, Arctic setting, Norwegians and group alone left wondering who the antagonist is. This is a neat little film I found cross referencing Donald Sutherland films I haven't seen before. The Nazi U boat subplot is also great for its atmosphere. Another bonus is that it offers a pretty good line up of old school actors such as Richard Widmark, Loyd Bridges and Christopher Lee. There aren't many great films about the Arctic but this is one that you will enjoy.
