Asaph and his boss talk about a type of desirable, exciting woman as a "tiger woman." This term came into use from 1929, with the publication of an autobiography of that name by Betty May, a femme fatale who was involved with drugs, crime, and the occult.
The explanation of the title occurs around 35 minutes into the film.
In 1954, Charles "Charlie" Ruggles starred in a sitcom called The World of Mr. Sweeney (1954) but it has no relation to this picture.
Charlie Ruggles was borrowed from Paramount.
