Fred Astaire introduced "Night and Day" on stage, and his recording of the song was a #1 hit. He performed it again in the 1934 film version of the show, renamed The Gay Divorcee, and it became one of his signature pieces. The song itself became an American standard and has been recorded by dozens of artists.
The song was so associated with Porter that when Hollywood first filmed his life story in 1946, the movie was entitled Night and Day.
Night and Day, is a 1946 Technicolor Warner Brothers biographical film of the life of American composer and songwriter Cole Porter. It was directed by Michael Curtiz and produced by Arthur Schwartz, with Jack L. Warner as executive producer. The screenplay was by Charles Hoffman, Leo Townsend and William Bowers.
The music score by Ray Heindorf and Max Steiner was nominated for an Academy Award. The film features several of the best-known Porter songs, including the title song, "Night and Day", "Begin the Beguine" and "My Heart Belongs to Daddy".
The film stars Cary Grant as Cole Porter and Alexis Smith as his wife of 35 years, Linda Lee Porter Monty Woolley and Mary Martin appear as themselves and the rest of the cast includes Jane Wyman, Eve Arden, Alan Hale, Dorothy Malone, Donald Woods, and Ginny Simms.
The film is a highly fictionalized and sanitized version of Cole Porter's life, leaving out amongst other things references to his homosexuality. A later film biography of Porter, the 2004 De-Lovely with Kevin Kline, dealt more frankly with his sexuality.
