Synopsis : Adapted from the novel by John Wyndham, this intelligent British monster movie begins with a meteor shower so intensely bright that it blinds the majority of the world's population, rendering them vulnerable to attack from hordes of carnivorous plants known as "Triffidus Celestus" grown from meteor-borne spores.
As the plant-monsters continue to multiply and seek human prey, the remaining sighted people join forces to combat the veggie invaders. One such survivor, an American seaman (Howard Keel) whose eyes were bandaged during the meteorite impact, battles his way through the Triffid ranks. Meanwhile, a couple (Kieron Moore and Janette Scott) are trapped in a lighthouse.
Good production values make this low-budget effort look more expensive than it probably was; the uncredited assistance of Freddie Francis -- who directed several scenes with a second unit -- also helps. Cavett Binion, All Movie Guide
