What language is this in?

Sorry to be asking what might seem a fairly naive question, but can someone tell me what language this film is in? I see the main IMDB page describes it as being in Russian and English, and the only trailer that I have been able to see for the DVD (on the Vox Video website) seems to have Russian dialogue, but it is diffiult to tell if this has been dubbed for the Russian market or not. As I have not seen the actual mini-series here in Australia, I thought someone here might be able to enlighten me.

Many thanks.
