1. "Dear Santa" letters were up by 25% in 1947 after movie-goers saw the 21 sacs of mail sent to Santa in the 1946 movie.
2. Edmund Gwenn, who played Kris Kringle in the movie, also played Santa Claus in the Macy's Thanksgiving Day Parade of 1946.
3. Edmund Gwenn's character replaced the drunk Santa in the parade. In 1948, the New York Times magazine reported a "Santa who grabbed a trim young mother, set her on his knee and suggested they both go out and have a drink".
4. In the opening scene of "Miracle on 34th Street", Edmund Gwenn's character walks down a New York City street and notices Santa's reindeer in a store window. Rudolph, however, is missing. While Rudolph had already been invented in 1939 in the Gene Autry song, he did not become popular until the 1964 TV special "Rudolph the Red Nosed Reindeer".
5. Edmund Gwenn's character was given a psychological test in which he had to answer a series of questions including "Who was the Vice President of the United States under John Quincy Adams?" He answered it incorrectly by saying "Daniel D. Tompkins." The correct response should have been John C. Calhoun.
6. The headline "'Kris Kringle Krazy! Kourt Kase Koming Kalamity!' Kry Kiddes" was probably inspired by the absurd headlines run by the Daily Variety in the 1940's and 1950's including "Sticks Nix Hick Pix".
7. The Santa suit that Edmund Gwenn wore was auctioned for $22,500 in 2011.
8. A little Dutch girl meets Santa at Macy's and sings the traditional Dutch song "Sinterklaas Kapoentje". Edmund Gwenn's character, who happens to speak Dutch, sings along with her.

11. Screen writer Valentine Davies was inspired to write "Miracle on 34th Street" after Christmas shopping in 1944.
12. Edmund Gwenn grew a white beard and gained 30 pounds for the role of Kris Kringle. He won an Oscar for his performance.
13. Three hundred thousand children each year sit on Santa Claus's knee at Macy's.
14. "Miracle on 34th Street" could have been called "It's Only Human", Mr. Kringle of 'The Big Heart;".
