When Nastya calls and the officer picks up Igor's phone he tells Igor that she told him that Nastya wants to give Igor a kiss from her and the officer says no way but when Artyom says in Russian I'll kiss the office, come here the officer said your crazy and shook his head as if he understood. How could the officer possibly understand what Artyom was saying if he is African American and doesn't speak Russian.
When Igor comes to Nastya's house William opens the door and Nastya's daughter has cue cards ready so that she can cue Igor on who the guy who opened the door is and what Igor did wrong for him to be there. How did Nastya's daughter know Igor would be there at that moment when William was going to be there, he came on the spur of the moment but yet she had cue cards ready for Igor.
When Igor, Artyom, and Sauna get arrested the officer asks them where are they from and they say Russia, yet the officer says that he doesn't know how they do it in Chernobyl but here in America someone can't drive on a red light. Chernobyl is in Ukraine not Russia.
