This is truly one of the great musicals to ever grace the silver screen. Between the great song, the dance numbers and the chemistry between Bing Crosby and Fred Astaire, this film really is one of the the all time classics. What really makes it great is that it pretty much plays like a great Broadway review that uses the different holidays as an excuse to display the individual talents of each of the film's stars. However, the thing that this film will truly be remembered for is the fact that it introduced one of the all time classic song's to the world, "White Christmas".
Another thing that makes this film so beloved is that it came out during a time when America needed somewhat of a diversion, World War II. This film helped to give people something to put smiles on their faces as the whole world was going to hell. At least for two hours, this film helped America to forget its troubles and put a smile on everyone's faces.
