How was polar express made?

"The Polar Express" was made using a combination of live-action and motion capture technology, with director Robert Zemeckis leading the project. Filmmakers captured the performances of actors, including Tom Hanks, using motion capture suits, which translated their movements and facial expressions into digital characters. The animation was then created by blending these performances with detailed CGI environments, resulting in a visually immersive experience that replicates the magic of the original children's book by Chris Van Allsburg. The film was released in 2004 and is known for its unique visual style and heartwarming story.
