Here's a question about a TV show I seem to remember from decades ago, in such vague detail I can't entirely rule out the possibility it is entirely a product of my fevered imagination. Sometime between very roughly the mid and late seventies, I'm sure there was a kind of documentary series on science fiction in both film and books that ran around teatime, possibly on BBC2. They interviewed writers like, I think, Michael Moorcock and Brian Aldiss. The opening credits featured a kind of line-drawing animation where a dragon would turn into a spaceship, would turn into a ... whatever. There might have been perhaps half a dozen episodes of it, possibly on the weekend.
If anyone has even the vaguest recollection of some series matching this, I'd be very grateful to know I'm not actually accidentally making it up, and what the hell it's called if it actually does exist.
