ive just watched kidulthood on dvd, before the film starts there are 2 or 3 trailers for new films, one film advertised was most likely a scene from the film im looking for, but it is basically a room full of men all numbered and carrying guns, a man is shouting out instructions for a game which is obviously a version of russian roulette they put one bullet in the gun point it out the head of someone in front(there all in a line) and are told as soon as the light comes on they must shoot, i never got the title. anyone no it
