There were fewer commercials on network television when this special was made. When shown recently on ABC and ABC Family, sometimes the special is edited in order to accommodate more commercials. In the ABC version, the songs "If you Sit on My Lap Today" and "My World is Beginning Today" are cut, while the ABC Family version cuts out scenes that may be traumatizing for younger viewers, most notably the scene where Burgermeister Meisterburger burns all of the toys belonging to the children of Sombertown.
Mickey Rooney would later reprise his role of Santa Claus in two other Rankin-Bass specials, 'The Year without a Santa Claus' and 'Rudolph and Frosty's Christmas in July', and the sequel to 'Year without a Santa Claus', 'A Miser Brothers' Christmas'.
The drawing of the king in Tanta Kringle's book, the doctor that treats the Burgermeister after he trips on the toy, and the father of the family that has their toys left in stockings are all the same puppet, complete with diamond-shaped eyeglasses.
During the scene where Kris gets captured by the trees, for 3 frames a man's arm and a flashbulb could be seen right when the flash occurs, before the winter warlock appears. This was fixed on later broadcasts and DVD releases.
