Yes, it was - it was originally a novel written by John Wyndham in 1951 and the story alluded to but did not confirm that The Triffids were creatures apparently bio-engineered in the Soviet Union and accidentally released when an aircraft carrying their seeds crashed (or was shot down).

Considering when it was written, the content and the pseudo-political backdrop it was something of a break-through for sci-fi novels - Arthur C Clarke is claimed to have called it an "immortal story".

I just thought that Jo was hot when I was a kid so I thought I'd watch it again.



Oh and I read the book in High School too.
