Besides Hero Boy, Hero Girl, Know-It-All and Billy, several other children are seen onboard the Polar Express in both the book and film. While they are not referred to by name in the movie, their names are revealed on a model sheet that is featured in The Art of the Polar Express.
Behind the scenes
Sometimes, a specific shot was framed to avoid having children appear because scenes with large amounts of children on-screen proved to be expensive. Initially, shots that did feature more children caused Maya to crash frequently. The animators went around this by splitting the scenes into smaller parts and putting them together after they were rendered.
