Whilst the majority of the film is in Russian, there are a few limited lines in English. Most of these are spoken by Vadim (the diplomat who presumably was stationed in England or the US). Interestingly, all of the lines are in the context of the film, they are reasonably well pronounced, which is enough to fob off the waiter in the restaurant. Amazingly, during a beach scene Zoya assertively responses back to one of the flirty one liners, albeit in Russian.
