Last Woman on Earth

A 1960 American science fiction film produced and directed by Roger Corman. Shady businessman Harold Gern (Antony Carbone), his wife Evelyn (Betsy Jones-Moreland), and his lawyer Martin Joyce (Robert Towne, in his screenwriting debut, credited as Edward Wain) are scuba diving off Puerto Rico when a mysterious temporary absence of oxygen kills everyone on the island — and possibly the world. When they surface, they find themselves the sole survivors of an unexplained apocalypse. As the three adjust to their new existence, the tension of being the last people on Earth — with only one woman — drives the two men into a deadly rivalry. Shot in Puerto Rico on a low budget, the film features an early screenplay by Robert Towne, who later won an Oscar for Chinatown (1974).
