Other mistake: The narrator says that the train stopped to let the train filled with Christmas carolers go by, but the train passed after the train had already crossed the tracks, so there was no need to wait. (00:19:30)

1 other mistake - chronological order
Directed by: Arthur Rankin Jr., Jules Bass
Starring: Paul Frees, Billy De Wolfe, Jackie Vernon, Jimmy Durante
Continuity mistake: When Frosty gets off the train because Karen gets sick, from the magician's view it appears the train is slowing down and is very close to Frosty, but when the shot goes back to the magician, the train appears to be going much faster and is much further away.
The Magician: We evil magicians have to make a living, too.
