Wonderful film, wonderful director: Basil Dearden, who also made Sapphire, one of the first British films to deal with race relations (it's not available on DVD), and Victim, the film that helped change the homosexuality laws in Britain in the early 60s.
But "The League of Gentlemen" outdoes them all for its wit, it's story and its cast-Jack Hawkins as Colonel NJG Hyde "Just let me say that I outrank you," who sends a group of ex-army officers fallen on hard times copies of a cheap American thriller with the plot for what he feels is the perfect crime. He gets them to go along with his plan by inviting them to lunch (as befits officers and gentlemen) and springing the story on them there. (Watch for what has to be one of Oliver Reed's first screen appearances as the dancer who's auditioning upstairs for "Babes in the Woods"-priceless).The cast includes a young Richard Attenborough, Nigel Patrick, Bryan Forbes and a few other top-notch actors who proceed to pull a bank job in broad daylight. The ending has to be seen to be believed. It's on my top ten list of all time best crime films.
