DVD Goof
I am currently watching my copy of the movie on DVD (I prefer the original version to this one but like the remake) and noticed a goof at the 17 minute mark.
The day after Susan has her Thanksgiving dinner, it shows Kris walking at night, then cuts to a scene of NYC and a closeup of Kris polishing one of his boots. Immediately after this, it cuts to the same scene of NYC and the closeup of Kris polishing the same boot.
I had to go back and make sure I didn't accidentally replay that part but it's in there. Not sure what happened but poor editing.
