They rarely make them this way anymore — but they should. Based on the Rudyard Kipling story and packed with spectacle, humor, excitement and bold twists of fate, John Huston’s film of “The Man Who Would Be King”earns its crown as one of the screen’s great adventures. Sean Connery and Michael Caine — chins out, shoulders squared and with an occasionalsly wink — star as British sergeants Danny Dravot and Peachy Carnehan. The Empire was built by men like these two. Now they’re out to build an empire of their own: they’re venturing into remote Kafiristan to become rich as kings.
