Mr. A is an elderly Briton who does not know how to walk across a street without being struck by an automobile. It is unclear to me how he lived so long and got to the location of the shooting of this British instructional film. However, this week I was at a New York doctor's office in which there were instructions on how to wash your hands over the doctor's private sink: not that hand-washing was required, but how to do it. Because a practicing doctor these days has no idea of how to wash his hands.
Likewise, we are confronted in this movie of an elderly man who has lived through a couple of world wars, the Blitz, the rise of the automobile without being confronted with the dread prospect of walking across a road. Yes, I know. This is a humorous handling of the subject, intended to make it clear to people who might not be aware of it, that crossing is best accomplished through the pedestrian walkway. However, there comes a point at which the artistic assumptions of anything explode and make the viewer look at it in well deserved contempt. This is one of those times.
