Why did Witek speak to Lilja in English?
I'm not sure if this is a goof or intentional. When Witek confronts Lilja after she screams for help, he speaks a few words angrily in Polish. This is fine and believable that in anger he speaks his native language - but it's very unlikely that Witek would not have a working knowledge of Russian. As an older Pole in his 40s-50s, he would have had Russian for a decade or so in school. If he was unable to communicate in Russian, what about his relationship with Andrei or other Russian/former Soviet contacts? How would they communicate? Broken English? Swedish?
I wonder if Witek is meant to know Russian, but because the character would rather limit his interaction with Lilja he does not speak with her in Russian. Or he limits his Russian use to business, never using it unless he has to.
My thoughts - he knows, but further adds to her dehumanization by refusing to give her even the comfort of a language she is familiar in. It gives him some advantage over her in a sense too, she isn't aware that he could understand her outside of English.
Maybe it's too deep for the movie, but I wonder to what extent the character of Witek being Polish and not speaking to Lilja was intentional..
What do you think?
