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.
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 The Bishop's Wife (1947), released the same year, and a performance that many believe was far more worthy of the statuette.
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).
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.
Loretta Young's Best Actress win for her role as Katrin is, to this day, one of the most stunning upsets in the history of the Academy Awards on two fronts: it was the first time a comedy performance had garnered the award since Claudette Colbert's win for It Happened One Night (1934) (1934), and it was generally assumed that Rosalind Russell would win for the far more dramatic film version of Eugene O'Neill's Mourning Becomes Electra (1947) (1947).
