I saw this film as part of Seattle's Paramount Theatre Silent Movie series (augmented by live Wurlitzer organ). Aspects of it (which you'll note if you can find it - I won't ruin it for you) were especially poignant in the light of the (at the time I saw it) Russian Kursk submarine tragedy. It lets you know exactly what the men of the Kursk were going through - no lie. Also notable were aspects of male/female relationships which have (publicly) changed greatly since this film was made (and come around again). If you can rent it, catch it on the telly, or see it in a theatre (best) - DO. Historically perspective drama at its finest.
