OK, I admit that I’m sharing this clip just because I like it. The scene unfolds in one long take — that is, without any edits and shot with a single camera. Our two heroes (played by Peggy Cummins and John Dall) are on their way to rob a bank. That’s all you need to know. Notice that when Cummins gets out of the car (a natural place for a cut), the camera merely follows her out the door.
But great moments in film music are also made by the absence of music, as in the famous biplane scene in “North by Northwest.” There is no music in this “Gun Crazy” scene until the bank’s alarm goes off, which adds to the reality of the sequence.
