I haven't seen this one brought up here, yet, and just stumbled on it tonight while I was investigating an old radio adaptation of the story. link

$this->bbcode_second_pass_quote('', 'T')he BBC's remake is set in 2011 when the world's fossil fuel supply is almost gone and the Triffids are being used as an alternative fuel source. According to the BBC's press release, the Triffids will roam the planet "with a fatal sting and a retributive taste for human flesh". A sighted survivor, Dr. Bill Masen, must lead an epic battle against the Triffids’ reign of terror, while avoiding the maniacal opportunism of other sighted survivors, to prevent the last days of mankind.
