'Holiday Inn,' the song 'White Christmas' was used again in the 1954 film musical of the same name.   It was supposed to reunite Bing Crosby with his partner from Holiday Inn, Fred Astaire, but Astaire didn't care for the script and turned the role down.  Donald O'Conner was said to have been offered the role, but he also turned it down, this time not because of script problems but due to an illness.  The part eventually went to comic actor, dancer and singer, Danny Kaye.

The film also starred famous Hollywood stars Vera Ellen and Rosemary Clooney.  Vera Ellen's singing voice was dubbed by singer Trudy Stevens except in the big number 'Sisters.'  For this song Rosemary Clooney actually sang both parts, harmonizing with herself.  Ironically, on the soundtrack album for the film, Rosemary Clooney, who was contracted to Decca records, was not allowed to record her voice on the Columbia label.  Instead, if anyone has a copy of the classic LP tucked away in their old album collections you'll notice that it's really Peggy Lee doing the singing.

The film was the first film to use Paramount studios' new cinematic process, invented to compete with television, called VistaVision.

Some things to look out for:  You'll notice that every Vera Ellen costume has a high neckline.  The actress had an on-going battle with anorexia throughout most of her career.  Because of this, her neck was described as looking like a 'chicken-neck,' aged and lined, which she requested to always be covered.  Also, the set of the Inn as used in the film is the same one used in the 1942 film 'Holiday Inn.' 

Bing Crosby is said to have ad-libbed much of his dialog, and even though Rosemary Clooney's character is supposed to be Vera Ellen's older sister, she was, in fact, seven years younger.  And in case anyone's wondering... yes, Rosemary Clooney really was George Clooney's aunt.
