I am a Soviet submarine officer, retired. I have to notice that this film contains a lot of fakes. Here the fakes I faced with during first 10 minutes: 1. We never rose our greatcoat collars, 2. In Russian (as well as in Soviet) army it is forbidden to give a salute without headress, 3. It is absolutely impossible if a Soviet officer get married in church. All Soviet officers were members of communistic party and marriage in church was considered as a breach of discipline. 4. There is no benches in Russian Orthodox churches. 5. The Captain wears American underwear. 6. The Captain of Soviet submarine is an epileptic??? This is an absolute nonsense. 7. Names of Soviet officers - Demy, Bruni, Alex??? 8. Any Soviet officer was restricted to travel abroad except maybe socialist countries and in the film the character travels to New York! 9. Submarine technician officer is a claustrophobic????
