It's my favourite sporting event ever, the 1978 match. Not just my favourite chess match, my favourite anything match, and I'd like a film about it to live up to that status.
You can't judge a film by its trailer, but my impression is that I'm liable to be disappointed, and to explain why, I want to make reference to a book I like, which is Edmonds and Eidinow's Bobby Fischer Goes to War (Faber & Faber, 2004).
You might say that you know more, after reading a good book, than you did before you read it, and that's true of Edmonds and Eidinow. But it's also the case that a good book leaves you knowing less, that what you thought you knew turns out not to be so simple, and that's what I liked about it most. Fischer v Spassky has been sold to us as the one-man band against the system, the lone genius against the Soviet system: and truth by told, that's part of the story, that's a theme you couldn't properly leave out.
But Edmonds and Eidinow write such that your sympathies aren't divided quite so unequally by the end. By then you probably like Fischer less than Spassky, and more to the point you probably like Fischer's entourage a good deal less than you like Spassky's, never mind the political systems behind them. It's not the story you expected, but it's a truer one, and a more detailed one, and it doesn't stop you thinking that Fischer was a lone genius against the Soviet system nonetheless.
Of course when I say "you" I mean the general reading public, since if you're a chessplayer, you might well already have a more nuanced and complex view of that match than other people. But it's that public, as well as chessplayers like us, which was well-served by the Edmonds/Eidinow book.
Will the cinema-going public be equally well-served by Closing Gambit?
