And I really got hot
When I saw Janette Scott
Fight a triffid that spits poison and kills. . .
Meteor shower blinds most of Earth's population, and if that isn't bad enough there are mobile, acid-spitting plants out to eat the few sighted survivors.
Great concept and some decent performances are both badly let down by some wretchedly flaccid direction which makes the whole production lack any sense of urgency or suspense. The absurdly happy ending is an affront to John Wyndham's source novel, but that's hardly surprisingly given Wyndham's generally poor treatment by cinema.
That all being said, there are some quite memorable bits here, but the ones that really hit home are the horrors of being trapped blind and helpless on a moving airplane or train, and not the killer plants, whiich are frankly silly-looking. Probably the most important aspect of this film is the image of people shambling aimlessly around a deserted metropolis, and survivors besiged by a horde of menacing creatures; both obviously the basic template for the zombie genre we know today. One does wish that Sekely did tell his 'blinded' extras that blind does not mean standing around in a daze as if you couldn't remember where you left your wallet, though.
Note: Victor Brooks is prominently credited, but he can only be briefly seen as the main convict in the French manor house, without any lines surviving, if he originally had any at all.
