Epic WTF

Late 70s, was working at a British Aerospace factory, they had to get the police, MOD as I recall, in due to the amount of tungsten that was going missing from stores and being turned in to darts.

This is just begging to be turned into a very British film. Could be a Guy Richie film, in which Vinnie Jones is using a darts tournament as cover for a bank job; the tungsten is really intended for drills to get into the hardened vault, but one of his gang can't resist diverting some of the tungsten to make high quality darts for his favourite darts player and this creates an evidence trail that puts the police on their track.

Could be a Full Monty kind of thing, where a bunch of the factory workers are a hopeless darts team, but one of them has managed to get them into a tournament under false pretences and hopes the tungsten darts will give them an edge; they fail in the first round but, heart-warmingly, the publicity mends the relationship between him and his estranged son.

Could be a Mike Leigh film; a shop steward organises a protest to hold up a delivery of tungsten the company needs, until such time as it gives proper support to families of workers who have suffered industrial accidents. But privatisation is looming and a middle manager whom he thought was a friend and ally sneakily flogs the tungsten to a dodgy darts manufacture so he can buy shares in the public sell-off. The bastard pins the blame on the shop steward, who not only goes to prison for a crime he didn't commit but is now reviled by his former coworkers as a fraud and a traitor.
