Corrected entry: When Arthur Lowe, John Le Mesurier and Clive Dunn are walking across the street at the beginning of the movie, you can see the "Cats Eyes" in the centre of the road between each white line. These were not invented during World War 2.

Correction: "Cats Eyes" were invented in 1933 by Percy Shaw. In 1935, he opened a factory to manufacture them and a year later, the first 50 were laid in Bradford. They became popular throughout Britain in World War II. http://en.wikipedia.org/wiki/Cat's_eye_(road).
