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.

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.

The lighthouse sits on a fictional rocky island near the Tierra del Fuego archipelago at the southern tip of South America.

Before the building of the Panama Canal, the waters off Cape Horn were perhaps the busiest and richest shipping lanes in the world, connecting Europe and the western coast of The United States.

Denton is contented to retreat from the world and be away from the problems of civilization, and quickly adjusts to his new supervisor, old Argentine sea dog Captain Moriz and his youthful and innocent assistant Felipe.

He saves Italian wreck survivor Montefiore from the pirates' massacre, and together they wage a war of guerrilla tactics against Kongre and his cutthroats.
