Technology about technology
Just noticed a constant tendency. In terms of wide adoption, motion pictures arrived after telephones, before radio, and well before cars and refrigerators and indoor plumbing. Even in USA STRONG cars weren't universal until after WW2 and phones weren't universal until 1970. Horses were delivering milk and mail in the '30s, and most people rode streetcars or buses. In other countries horses are still part of the transportation picture today.
But horses were NOT part of motion pictures in any movie-making country. USA, UK, Greece, Brazil, Turkey, Egypt, Mexico... In ALL of those countries,
movies were always filled with cars and telephones. Greek and Egyptian movies in the '50s and '60s always started with a car chase scene, and distraught or catty women were constantly talking on the phone. Kitchens were always up to date. Fridges, plumbing, electric lights, radios.
Movies have always been technology about technology. If you wanted to see a horse, you had to find a
historical movie about kings and queens and knights and cowboys of earlier centuries.
