Like another reviewer from Samara has mentioned here, you can count tons of fakes here. Usually a Hollywood movie at least tries to be as much accurate as possible. Here, apart of gears showing authentic Russian readings and navy/military uniforms looking right, everything else looks and feels American. I can mention few "gems" here, like what and how "Russian" officers drink! They do not gulp (as any normal Russian does) - they sip, just like ladies. Then all these "sir" and "mister", and then a Russian captain reflecting and even crying about killed sailors. Really? And all those nice and glowing scenes from an Orthodox church! Yes, of course. Churches in Russia in 1960s. The director, Todd Robinson, should have hired just one Russian as a consultant, that would serve the movie for sure.
However, if you ignore the lines in the story that this is supposed to be about Russian people and Russian navy and few real things like those gears, and imagine that this is about a US navy, and about rogue CIA agents, then everything falls in its place and looks natural. This could be a good watchable movie.
