Audio problem: When the elves are marching around, listen to the footstep sounds and watch their feet. A lot of times the noise and movements don't match. This is especially apparent when the five elves who have been taking wish calls go to the transporter.
The Polar Express (2004)
1 audio problem
Directed by: Robert Zemeckis
Starring: Tom Hanks, Michael Jeter, Chris Coppola, Leslie Zemeckis
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.
Conductor: One thing about trains - it doesn't matter where they're going. What matters is deciding to get on.
Trivia: The ticket that gets lost often times floats almost exactly like the feather does in the beginning of "Forrest Gump" (1994), another Robert Zemeckis-Tom Hanks film.
Question: How would the train have been able to go back the same way with the ice on the lake cracking?
Answer: Because it's a magic train.
