- California Doubling: Set in Switzerland and London, but obviously filmed in California apart from Stock Footage.
- The Danza: When the background girls are given names, it's usually just the first name of the actress.
- Fake Nationality: African-American Judy Pace is cast as a girl from Liberia. This being the '60s, it goes without saying that the Russian girl is not actually from there. Lynne Sue Moon, who plays Mai-Ling, is the daughter of a Cantonese father and a British mother.
