The Beach: A River of Sand. This 1965 Encyclopedia Brittanica film shows us how ocean beaches are formed, what they are made of, and how they are parts of much larger geological systems. This sounds as dry as, well, sand, and it would be, except for how beautifully photographed and directed the film is. The striking imagery of beaches from all angles and distances holds your attention, making this a very successful educational film. As a Nebraska gal, I’ve only been on ocean beaches a handful of times, and this film makes me long for them. Ratings: Camp/Humor Value: *. Weirdness: **. Historical Interest: ****.
