The title of the film comes from a story told in drawings - The War Between Men and Women - whose author was the famous American humorist, James Thurber (1894-1961). Thurber's most famous work is the short story "The Secret Life of Walter Mitty" which was made into a movie starring Danny Kaye in 1947. A new version of "Mitty" is in production.
The character of Peter Wilson played by Jack Lemmon in this film suffers from failing eyesight which also plagued Thurber and contributed to his unique drawing style. This film was probably inspired by William Windom's portrayal of a Thurber-like character in a TV series broadcast in 1969 called My World and Welcome To It which is a title of one of Thurber's books. Windom went on to do a one-man stage performance of Thurber's works including some animation of some of Thurber's drawings. At the end of The War Between Men and Women we see one of these animations, an anti-war piece by Thurber called "The Last Flower".
