Last Woman on Earth (1960) is one of three movies that Roger Corman made in Puerto Rico. He made Creature from the Haunted Sea (1961) back to back with Last Woman on Earth to save money (shoot two movies while on location in one place). Last Woman on Earth is probably the better of the two. It was written by renowned screenwriter Robert Towne (Chinatown (1974), The Last Detail (1973)) and feels kind of like an old episode of The Twilight Zone (1959-1964).
