Another of his that I really like is The Outward Urge (with Lucas Parkes) on the idea of yearning for space travel as a heritable thing passed down several generations of a family, over an implied world war and shifting of nation powers.
Another good more popular one is The Midwich Cuckoos (filmed as The Village of the Damned); all the women in the village became pregnant overnight, what did it mean and what to do about it? (Spoiler below). "Midwich was not the only - or even the first - village to have a dayout".
One I liked less, Chocky, an alien "invasion" by telepathy which turned into a bland rushed lecture on wasting fossil fuels and had no interesting conclusion.
(spoiler: aliens)
From wikipedia
> The story grew out of Ellis' question as to what would have happened if the Midwich Cuckoos had survived and grown to "disaffected and confused twenty-one-year-olds." The story builds on the legacy of John Wyndham's style of disaster fiction
The www.freakangels.com website appears to be down, unfortunately which might have something to do with Warren Ellis' more recent disgrace (https://www.somanyofus.com/) but it used to have the whole story available for free.
There is a recent video adaptation available too: https://www.youtube.com/watch?v=Ppb1OnVEF7A
As a John Wyndham fan, I reckon it's about time there was a film version of The Kraken Wakes.
I'm a big Lovecraft fan and have tried to watch as many of the video versions as possible, but most of the adaptations turn out to be fairly rubbish. Color Out of Space was good fun though. I think the best Lovecraftian films are not directly related and I'd recommend AM1200 as an excellent short that gives a really good Lovecraftian feel.

Mind you, we also had Jim'll Fix It so a bit of horror wasn't the worst.
Unfortunately it had Gary Glitter in it playing a fairly major character so unless someone dumps a ropey old VHS of it onto Youtube it's never going to be seen outside of Granada Television's deepest murkiest vaults.
Though I'd love to see it done as a faithful alternate history/retro-futurism thing too.
Go make it.
