The seemingly benign and lighthearted surface belies the sharply satirical teeth of this film, which aims fairly and squarely in all directions and hits most of its targets - class, establishment, industrial relations, etc. - with ease and good grace. Fifty years haven't dimmed the feeling of 'twas ever thus with arms dealing and corporate connivance as pertinent now as then.
among the things i always envied the brits was their sense of satire. they hold nothing sacred and are willing to poke holes in order to bring certain points of life to light in smart and sometimes acerbic ways. "...jack" doesn't give a hoot about class and social affiliations and the whole movie is made stronger by the wonderfully superb cast.
