When we first meet Johnny, he flashes back to his childhood, singing in his bedroom. We are indicated it is fifteen years earlier by an on screen note. As the scene progresses and we see more of the boy's room, a Playstation video game console can clearly be seen under the boy's television. If the movie took place in the year 2008, this scene would be taking place in 1993, but this console was not released until the end of 1995.
In the scene where Lenny tells his henchmen the painting's been stolen, Bandy asks "where was it then?", his shirt collar is unbuttoned, sticking out of his jacket. Though when the camera cuts back to him, he is wearing a tie and his collar is buttoned. Then when it cuts back to him, his collar is unbuttoned and sticking out again.
During the flashback to Johnny's childhood, Lenny switches off his stereo. As he switches it off, he pushes the top part of the stereo out of place. When the camera pans back out, we can see that the stereo is back in the correct position.
On the golf course, Uri advises Lenny that, because they are on the ninth hole, it will take him until sunrise to get back to his car. The ninth and eighteenth greens are often closest to the clubhouse, however many traditional British links style courses have ninth holes that are the furthest point from the clubhouse. This is the basis of the expression, "at the turn" in golf. After the ninth hole, the golfers will turn around and the remaining holes will lead them back to clubhouse. This is also why scorecards say "out" referring to the score on the front nine and "in" for the back nine.
Majority of the Russian lines in the movie don't correspond to the translation shown. Mostly the overall approximate meaning of a passage or dialogue is preserved, but even that is not always the case.
