The Light at the Edge of the World is a 1971 Spanish-American adventure film, directed by Kevin Billington and starring Kirk Douglas, Yul Brynner, Samantha Eggar, and Fernando Rey. It was adapted from Jules Verne's classic 1905 adventure novel The Lighthouse at the End of the World (Le Phare du bout du monde). The plot involves piracy in the South Atlantic during the mid-19th century, with a theme of survival in extreme circumstances, and events centering on an isolated lighthouse.

Despite having a large Hollywood budget, collaboration with prestigious foreign film studios, exotic shooting locations in Europe and some of the biggest name movie stars, the movie was mainly a failure at the box office.
