Just after Maria's engagement is announced, Harry is in a small town near a seaport talking to a group of men. They are all looking and gesturing off to stage left. Maria drives right up behind the group and sounds the car horn. The group of men continue talking for almost 3 seconds before any of them react to a car horn that is supposedly going off just 5 feet behind them.
