This film is very underrated on this site. It is in a genre that is not really made very often any more--action adventure that is plausible both in plot and technology. And the action adventure plays equal footing to the actual acting and dialog. It is closer to an World War II action film than to, say, one of Arnold Schwartzeneger's action films.
As an artistic piece of work, the lack of women (and any romantic story) keeps this cold war picture completely focused on the primary story, and makes the actors work all that much harder to keep the viewer engaged.
There is also a good bit of spectacular on-location filming that still takes your breath away with its beauty. The actual polar icecap scenes (with actors) where the focal point of the movie's action takes place is a set. And it is a glorious one. No CGI imagery here! I bought this DVD for this film in a bargain bin. If you get the chance snap one up, or rent it and watch it on a decent TV. Great transfer.
Good score as well.
