Jules et Jim
First of all, this movie was absolutely brilliant. The only thing that detracted from it was the B-grade English-speaking actors, but that's more of a problem with the cost of decent English-speaking actors due to Hollywood's monopoly, and has been discussed in other threads. The Korean actors were perfect, and every film I see with Song Kang-ho and Lee Byung-hun just makes me a bigger fan of them.
Anyway, was anyone else reminded a little of François Truffaut's 'Jules and Jim' while watching this movie? Although it wasn't a huge part of the film, when Jules and Jim are sent off to fight on opposite sides of the war, we see that their friendship is far above the conflicts and ideas of their separate countries. That was always one of the things I remember most about the movie.
It was almost as if JSA was a film centered completely around this idea in Jules et Jim, and done so very well I might add!
