The screenplay was by Claudine West, Jan Lustig [de] and George Froeschel, with the credit for additional poetry by Robert Nathan.

Nathan stated in an interview that he wrote the screenplay as his first work as a contracted writer for MGM but the studio credited Claudine West who died in 1943 as a tribute to her.

[3] At the height of World War II, American-born Susan, Lady Ashwood, (Irene Dunne) is a nurse in a British hospital, awaiting the arrival of 300 wounded men.

In 1914, Susan and her father, small-town Rhode Island newspaper publisher Hiram P. Dunn (Frank Morgan), come to Britain, intending to stay for two weeks.

Old Colonel Forsythe (C. Aubrey Smith) introduces Susan to Sir John Ashwood (Alan Marshal), a baronet and one of the landed gentry, with an estate and manor house.

The younger boy remarks that the estate's large lawns would be ideal for military gliders to land - a premonition of the airborne attacks launched by Nazi Germany.

Herbert Stothart weaves a number of evocative pieces of music through his score, including: "Auld Lang Syne", "Hurrah Boys, for England", "Land of Hope and Glory", "My Country Tis of Thee"/"God Save the King", "Home!

", "Sweet Afton", "There's a Long, Long Trail", "Do ye Ken John Peel", "The Minstrel Boy to the War Has Gone", "Pack Up Your Troubles in Your Old Kit-Bag", "The Star Spangled Banner", "The Stars and Stripes Forever", "Over There", "Vive la Compagnie", "Coventry Carol" (Woe is me, poor child for thee), "America (My Country, 'Tis of Thee)", "Greensleeves" and "When Johnny Comes Marching Home".

White Cliffs of Dover was adapted as a radio play on the September 18, 1946, episode of Academy Award Theater, starring Irene Dunne in her original film role.

In a 1966 episode of the game show, Password, Bunny Gordon, who portrayed John Ashwood II as an infant in an uncredited role, appeared as a contestant when Peter Lawford, who portrayed John Ashwood II as a young man, happened to also appear on the show as a celebrity guest player.
