I happen to have a spare five minutes, so in the spirit of "A Town That Cannot Always Be Found and Other Almost Forgotten Tales", may I present the happy ending of decades spent thinking about and searching for an animated film that I saw in my very young youth during the early-mid 1980s.
Here it is: Skywhales, a 1983 British animated short, starring the vocal talents of Robert Llewellyn (AKA Kryten from Red Dwarf). It's only 10 mins 41 long if you fancy a look.
The only thing I could remember about it was some sort of dying airborne whale falling down a big hole or chasm and getting wrapped in bandages like a mummy. And you'll see that what I remembered was a bit back-to-front, but the general gist was right.
I might as well also mention the Time Masters, or Les Maîtres du temps (as it is called in its original French) from 1982, too. I rediscovered this, rather longer animation, two or three years ago after various recollections of a little boy named Piel managing to escape from some giant wasps, then being guided across some alien landscape to safety (via a radio or communications device) by some people on a spaceship or space station. I also remembered a giant waterlily flower opening and releasing hundreds of fairies, and an old man on the space station (one of Piel's remote rescuers) dying after a fifty year time jump or something (and the revelation of who he was, which I'm not going to spoil in case anyone wants to watch it).
The video above is the only one I could find on YouTube in English, and is not as long as it seems as the film ends at 1:14:00 (or thereabouts) before starting again. Here's a link to the Hungarian (I think) version which seems to be about the right length (I haven't watched it all).
Have any of you had any success in finding half-remembered childhood films, cartoons or books?
