Waaaayyyy back in years of yore, when I was about fifteen or so, I used to catch a ride with a man named Larry Something to meetings of the Atlanta Science Fiction Club. Those being the years before widespread availability of videotapes and DVDs and such, Larry would sometimes set up an actual film projector and show rented wonders to us, the assembled nerds. I recall really enjoying these, though I only remember two of them specifically. One was the great Star Wars spoof Hardware Wars (with Ham Salad, Augie Ben Doggie, and Chewchilla the Wookiee Monster, and findable on YouTube).
The other was a marvelous short called The Sand Castle, an evocative piece of stop-motion animation depicting an engaging group of sand-formed creatures cooperating to build the titular castle. I thought it wonderful, and looked for it here and there over the years, particularly once I became a dad, but without luck.
Well, I found it. Turns out it was a product of the National Film Board of Canada, which has now made tons of their stuff available online. And The Sand Castle seems to have been quite a collector of awards, including a Short Film Oscar.
It’s just as cool as I remembered. Check it out:
