John Ford's "Fort Apache" (1948)

'Two of the most beautiful things in the world," Ford was fond of reminding his scenarists, "are a horse running and a couple waltzing." (...) "With Ford," said Flora Robson, one of the 7 Women, "the actor is continually conscious of the fact that he is making a motion picture and that it must move, move, move. His scenes are never static or dominated by the dialogue." "When movies are best," said Ford, "the action's long and the talk's short. When a film tells its story and reveals its characters to us in a suite of simple, beautiful and animated shots, that's a movie.'
