The Hollywood version, 1962, was, well, typical Hollywood with Howard Keel of all people. They saved the world with salt-water!
The BBC did a version for television in 1981 which I recall as being very close to the original.
I read the book when it was first published in 1951 and re-read it fairly often. I had to replace the original with a 1989 printing from Del Rey which I still have.
The only other book of Wyndham's that I recall reading was 'Midwich Cuckoos'. I thought the first movie with George Sanders was pretty good, but didn't think much of the sequels and the version with Christopher Reeve didn't measure up IMO. I see from IMDB that they are supposed to release a remake for tv scheduled for August 30.
