Character mistake: The sign on the shopkeeper's door reads "Closed Thanksgiving Day November 28th 1947". Thanksgiving was on November 27th in 1947.
Continuity mistake: When Dr. Sawyer is giving Kris the exam, during the part where Kris is doing the physical coordination test, we see Kris from Sawyer's point of view, and Sawyer is drumming his fingers. When the shot switches to Kris's, he is fingering his eyebrow. When it switches back, fingers drumming. Finally, when it switches back again, his hands are neatly folded in front of him.
Visible crew/equipment: When Kris is being taken to the court house, when he meets Alfred before getting on the elevator, the camera pulls in for a closer angle, and you can see the camera mobile's shadow on a pillar to the left.
Other mistake: The traveling camera used during the opening credits is not positioned correctly; it is tilted to the right, causing the whole scene to be crooked.
Continuity mistake: The note that Susan wrote to Santa Claus changes in writing style between the time it's first shown and the time her mother signs it seconds later - the words "Yours Truly, Susan" are written completely differently the second time. (01:23:30)
Character mistake: In the scene where Kris's knowledge is being tested, he incorrectly gives the vice president of President John Quincy Adams. Kris states John Quincy Adams' vice president was Daniel D. Thompkins. That's wrong. John Quincy Adams' vice president was John C. Calhoun. Daniel D. Thompkins was the vice president under President James Monroe.
Continuity mistake: In the opening scene, the guy bothered by Kris Kringle about the authenticity of the reindeer display is leaning in different positions between the front angle and its reverse. (00:02:00)
Answer: Not sure of the dialog but here is the Christmas Carol they sing, the lyrics are: Sinterklaas kapoentje, gooi wat in mijn schoentje, gooi wat in mijn laarsje, dank u Sinterklaasje. The translation is: Sinterklaas good man, throw something in my shoe, throw something in my boot, thank you Sinterklaas. Actually not a Christmas carol but a song for another holiday earlier in December.
