Was the Russian spoken in this movie accurate?

I mean, I don't speak Russian and I have no clue of this, but I always wonder if the foreign languages are spoken accurately in American movies, because they don't really care about this. As long as the American audience buy it, it's ok. Americans always tend to do that. In Stigmata, they send the priest to a city in Brazil and the native priest of the city spoke the worst Portuguese ever. A mixture between some sort of Portuguese and Spanish. I mean, they just kill other countries' culture. Also in the last movie of Twilight (yes, I watched it), the indigenous guy, the native man of Brazilian Amazon, OMG, his clothes were totally inaccurate... So, I was just wondering, if there's a native Russian here, the language was well spoken?
