The film takes place in the Alps but was actually filmed at Jasper National Park in Canada. Billy Wilder spent $20,000 to have pine trees sent from California and planted on location because he was not satisfied with the Canadian pine trees; he also planted 4,000 daisies that were painted blue because he felt white daisies did not photograph well.

Bing Crosby and Richard Haydn also worked together in 1950's Mr. Music.

The audio to the Emperor Waltz song was used for a Schiller Reel on Saturday Night Live, Dec 17, 1988: "Love is a Dream", featuring Phil Hartman and Jan Hooks, directed by Tom Schiller.

The song "The Kiss In Your Eyes" was given new words and a new name and became a popular hit for several artists in the late 1940s under the title of "Suddenly".
