Is the chess game in the movie Sherlock Holmes: A Game of Shadows real?  The characters call out their moves in usual notation, but the chess board isn't shown.

I haven't seen the movie yet but the credits (on IMDB) have Adam Raoof (I assume that is the same guy) listed a technical advisor for chess.

If the director didn't change things up to make it more interesting then I would guess it was a real game.

The chess scene was pretty cool, but so was the whole movie.

According to Adam Raoof, the chess consultant on the movie, "Actually not much of the footage of the actual game we filmed survived the edit, but it was a famous Larsen game with reversed colours and using some variations."

The game was based on Bent Larsen vs Tigran Vartanovich Petrosian (Santa Barbara 1966).

It must have been a variation, at the start of the move calling I believe it started with a Bishop sac, and ended with a discovery mate. I couldnt remember all of the moves being called out.

It was a variation actually. Also, the colors were reversed.
