[math-fun] Chess game in current Sherlock Holmes movie

I saw this movie yesterday. http://en.wikipedia.org/wiki/Sherlock_Holmes:_A_Game_of_Shadows Q: Is the chess game in the movie real? The characters call out their moves in usual notation, but the chess board isn't shown. For those of you chess nuts who can do chess in your heads, would this be a real game? I would imagine that after spending $125 million in making this movie, someone must have hired a chess person for a few hundred dollars to make the game real.
