One of the few movies where the "remake" was better. The movie "Stones For The Ramparts" 2014 (also released as Warsaw 1944) is based on the same subject. The real life story of a Polish group of underground resistance fighters called the Gray Army. The major beats are the same in both films but the second version is more involving. The cinematography in this earlier version is murky. The DVD transfer on the version I saw was horrible. Still, this version is watchable if you can't find the other one.
