This was not the war movie I expected. I figured that since it was about a famous member of the resistance movement, it would be about the sabotage they did, but that's only a small part in the movie's opening. Most of the film is not about the sabotage, but his escape. The enemy is obviously the Nazis, but just as much the fear of Norwegians giving him in, and most of all nature and the elements themselves. This makes for a much more interesting movie than I had anticipated.
That said, this is still an old movie, made in a small country which back then were not famous for their movies. The acting hasn't aged well, and there's some annoying editing that's obviously meant to cover up some difficult sequences. That said, there's also some really nice shots, and they actually went to the trouble of getting actors speaking the right dialects (or, mostly at least!).
This never felt like a very exciting film, but more like a slow, brooding reflection over what people went through during the second world war, and also just how dedicated people can be in helping each other.
It's a no brainer if your aim is to see a Norwegian classic, and it's not a bad choice if you want to see a different ww2-movie.
