The Mannerheim Line
Produced by the Soviet Union to justify its 1939-40 Winter War campaign in Finland, this outstanding documentary---more than any other such cinematic record---visually depicts the much vaunted Mannerheim Line in all its actual emplacements, as seen but two weeks after their capture, and as filmed by Red Army combat photographers onsite, directed by Vasili Belayev.
