The Polar Express (2004)

Continuity mistake: When the boy runs out of his house, as the train is arriving, they make a point of showing his footprints in the snow along with his sliding leaving long marks. However, when they pan back it is his footprints that are gone.

Hero Boy: At one time most of my friends could hear the bell, but as years passed it fell silent for all of them. Even Sarah found one Christmas that she could no longer hear its sweet sound. And though I've grown old, the bell still rings for me, as it does for all who truly believe.

Trivia: Whenever Hero Boy asks Hero Girl, "Are you sure?" some dramatic music is played. This is the same music that was used in the BTTF Trilogy whenever Marty Mcfly was called a chicken.
