Despite I live in Poland, I saw just a couple polish films in last 20 years. I was so disappointed with some of polish films I watched in 80's and early 90's that I completely stopped watching polish productions. Few ones I watched during 90's and 2000's were lame or just "so-so". I especially loathed the way polish actors play and speak - it was unnatural, theatrical.
But since I was interested by real story depicted by Jack Strong, I give it a try and I must admit this film is really perfect. There is still a little bit of this annoying theatrical manner when polish actors speak, but it is just a tint, and probably this is completely not detectable by non polish speakers. The rest is great - very realistic to smallest details (I still perfectly remember 70's & 80's during communist rule) Russians speak Russian, Poles speak Polish, Americans speak English. Filmed in real locations in real winter, with real snow. Real cars from 70, with real looking chases (and no CG or accelerated paces. Intelligent move for intelligent people in the same class like Argo or Der Baader Meinhof Komplex. Very refreshing experience after all those dumb nonsense full of CG served by Hollywood lately.
Let's hope this fill will be soon released on blu-ray, so more people outside Poland can enjoy this masterpiece.
