Behind the scenes
- "Corto Maltese" is entirely fictional, also appearing in Frank Miller's graphic novel Batman: The Dark Knight Returns as the name of an island at the center of an incident not unlike the Cuban missile crisis. It was later mentioned in the 1989 film Batman and the TV series Smallville. Miller likely took the name from a well-known Italian comic, Corto Maltese, about an adventurous sailor of the same name.
