On a cold day, Katrin (Loretta Young) prepares a drink called glogg for Glenn (Joseph Cotten). Glogg is usually made from claret, aquavit, sugar, cloves, cardamom, orange peel and raisins. It is ignited before being served.
Initially titling their film "Katie for Congress", RKO sought the more suggestive title "The Farmer's Daughter". However, they had to buy that title from Paramount Pictures, who owned The Farmer's Daughter (1940).
In this movie, Katrin Holstrom (Loretta Young) reads the story of the townsfolk who place their beloved doctor's office shingle as a monument on his tomb: "Dr. Sorensen: Upstairs". Essentially the same scene occurred in Dreaming Out Loud (1940), where Lum and Abner place the "Dr. Walter Barnes: Office Upstairs" shingle on the doctor's tomb.
One reason that Loretta Young's Oscar win was considered an upset, was because her character is largely absent from the second half of the film, as her character, Katrin, becomes the off-screen linchpin in a complex political plot. Ironically, Young had far more screen footage in La moglie del vescovo (1947), released the same year, and a performance that many believe was far more worthy of the statuette.
Although the state is never mentioned, it would appear that it takes place in Minnesota, where there is a large Scandinavian population. "Capitol City" would seem to be St. Paul, and the Morley's mansion certainly looks like it was on Summit Avenue. Glenn Morley's (Joseph Cotten's) political party is never mentioned.
