After a night at a roadside gas station and motel, Mr. Drake (Fredric March) asks Mrs. Drake (Loretta Young) to pay for her room. She says that she's out of cash, so she'll have to use her credit card. The use of the term credit card in this 1941 movie is curious. The first use of this term is attributed to Edward Bellamy in his 1887 Utopian novel, 'Looking Backward,' but the first real credit card (not to be confused with a single-vendor charge card, issued by department stores, airlines and the like) didn't come along until the Diners Club card was introduced in 1950. However, gas stations were beginning to accept each others' charge cards in the 1930s. Obviously, the names were being used interchangeably even before the likes of Diners Club, Carte Blanche, American Express, and various bank-issued credit cards appeared on the scene.
The Drake theater seen in this film was carried over and used in the production of Alias Boston Blackie (1942). Nothing was changed. The play "Bedtime Story" written by Lucius Drake was still playing. They hadn't bothered to change anything.
Casting problems delayed the start of production on this film for several months.
The hotel scene where Luke Drake sends the plumbers, housekeeping, exterminator, eight chicken dinners, and the conventioneers is very similar to the hotel scene in Foreign Correspondent (1940).
