'Dark Horse.' I asked for it once as a Christmas present.
I got it along with my chess mug, two chess books (one from a 2nd hand shop) and the obligatory chess tie.

But it was the wrong 'Dark Horse.'
Eventually got the right Dark Horse. (I'll lift part of my review)
It’s OK. All about a lad who was a good chess player but developed some social problems.
So to give himself something to take his mind of his own predicament and help out the poorer
kids in the neighborhood he joined in on starting up a Chess Club, The Eastern Knights (which is still going today.)
Not too much chess on display. There are glimpses to show the makers knew
enough about the game but chess takes a back seat as he and his nephew bond.
In one of the games you do see...this happened.
However White does go onto to win game. (we are not shown how.)
Have watched all chess themed films (well those I know of).
My opinion mostly agrees with Stewart's except 'Seventh Seal' which i thought was crap.
When I was kicking up my stink at the Edinburgh Filmhouse...
...for not showing 'Pawn Sacrifice.' The pretty girl after googling it said it was a film about 'chess.'
I said recently they showed that crap Swedish chess film.
The girl did not know what I was talking about.
(which is little wonder because I do not think they showed 'Seventh Seal' either.)
