One of over 700 Paramount Productions, filmed between 1929 and 1949, which were sold to MCA/Universal in 1958 for television distribution, and have been owned and controlled by Universal ever since. It was released on DVD 6 May 2003, in tandem with A Connecticut Yankee in King Arthur's Court (1948), as part of Universal's Bing Crosby Collection, and again 11 November 2014 as one of 24 titles in Universal's Bing Crosby Silver Screen Collection.
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.
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.
"Lux Radio Theater" broadcast a 60 minute radio adaptation of the movie on September 26, 1949 with Bing Crosby reprising his film role.
