Russian Speakers

Recently I saw a Russian made movie about Aliens crashing (After they were shot down by a Russian Cowboy fighter Pilot) in downtown Moscow (?) It was a very good movie in spite of the fact that I do not speak Russian. I am hoping that someone can name the lead Military man, and the girl who fell in love with the Alien. Anything else would be a bonus. I'd rather not simply call them Boris and Natasha.

I am thinking of writing a short fan fiction sequel.

Thanks
