The Day of the Triffids is a 1963 British science fiction horror film in CinemaScope and Eastmancolor, produced by George Pitcher and Philip Yordan and directed by Steve Sekely.

Later the place is invaded by escaped convicts and during the mayhem triffids move in and kill everyone except Bill, Susan and Christine, who manage to get away in the prison bus.

On their way they encounter a blind couple, Luis de la Vega and his pregnant wife, Teresa, and help her deliver a baby boy.

Masen gets de Vega's radio transmitter working just in time to hear the navy broadcasting a message about a final survivor pickup in Alicante the next day and a warning to beware of wandering bands of triffids.

In a last effort to hold them off Tom sprays them with a salt-water fire hose and the triffids begin to dissolve in a cloud of green smoke.

Although the film retained some basic plot elements from Wyndham's novel, it is not a particularly faithful adaptation: "It strays significantly and unnecessarily from the book and is less well regarded than the BBC's intelligent (if dated) 1981 TV serial".

[3] Unlike in the novel the triffids arrive from a meteor shower, some of the action is moved to France and Spain, and an important character, Josella Playton, is deleted.
