Two shades of mythical coldness

I read David Howarth's book Die Alone (1955) and noticed that it has been made into two films. Arne Skouen's Nine Lives (1957) and this Harald Zwart's The 12th Man (2017). An incredibly amazing survival story about a Norwegian soldier who, instead of carrying out a planned sabotage mission, flees the Nazis in perhaps the most barren and unforgiving terrain in the world. It also tells of people's selfless desire to help, even at the risk of the helpers risking their own lives and the lives of their families. The film is also excellent.
