In this film version, however, the Triffids are not indigenous plants. Instead they are space aliens whose spores have arrived in this and an earlier meteor shower. Derided by the original novel's author, John Wyndham, for straying so far away from the source material.

The original title for the show was Battleground: Earth, but the producers changed it because it sounded too much like L. Ron Hubbard's novel, Battlefield Earth. The executive producer was Majel Barrett-Roddenberry. She also appeared in some early episodes as the character Dr Julianne Belman. Barrett was in possession of notes Roddenberry kept of story and series ideas; after his death, these notes provided the basis for this series.
