For the "drunk" dance, Fred Astaire had two drinks of bourbon before the first take and one before each succeeding take. The seventh (last) take was used in the film.

Irving Berlin got the idea for the film after writing the song "Easter Parade" for his 1933 show "As Thousands Cheer", and planned to write a play about American holidays, but it never materialized. He later pitched the idea to Mark Sandrich who got the ball rolling for this film.
Some controversy surrounded the history of the song "White Christmas" when it was reported in a 1960 news item that Irving Berlin wrote the song in 1938. Had the song been published or introduced outside of the film, it would have been ineligible for an Academy Award nomination. But sources agree it was written for the film, copyrighted as unpublished in 1940 and then published along with the film's release in 1942.
The first public performance of the song "White Christmas" was by Bing Crosby on his NBC radio show "The Kraft Music Hall" on Christmas Day, 1941, during the middle of filming _Holiday Inn (1942)_, which was released seven months later. The song went on to become one of the biggest selling songs in the history of music. This was the first of three films to feature Crosby singing "White Christmas".
Until 1997, "White Christmas" was the best selling music single ever. It was passed at that time by "Goodbye, England's Rose", the Elton John rework of "Candle in the Wind" done for Princess Diana's funeral. These two songs still rank #1-2.

At the end of the first time Jim (Bing Crosby) and Linda (Marjorie Reynolds) sing "White Christmas" the fireplace seems to suddenly flare up and then die down. In an interview the Director (Mark Sandrich) admitted it happened when the stage hand controlling the gas flame in the fireplace turned the control valve the wrong way, up instead of down.
