Triffid? Triffic!

This 1981 adaptation of John Wyndham's cult novel has always been fondly remembered. The world wakes up blind, with a few sighted survivors left to work out a future for humanity, and see off the threat posed by man-eating Triffid plants.

This version of the book is much more faithful than the controversial film version, and was the brainchild of Blake's 7 producer David Maloney.

It starred John Duttine and Emma Relph, but the show is stolen by the Triffids, clacking away menacingly in the background, picking off the occasional character when the plot needs a lift.
