Cartoon The Polar ExpresThe Polar Express is a 2004 computer-animated feature film based on the children's book of the same title by Chris Van Allsburg.
Written, produced, and directed by Robert Zemeckis, the human characters in the film were "animated" using "live action" performance capture technique, with the exception of the waiters who dispense hot chocolate on the train, because their feats were impossible for real-life actors to achieve. Performance capture technology incorporates the movements of live actors into animated characters. It stars actor Tom Hanks in five distinct roles, including the role of Santa Claus. The film was produced by Castle Rock Entertainment in association with Shangri-La Entertainment, ImageMovers, Playtone and Golden Mean, for Warner Bros. The visual effects and performance capture was done at Sony Pictures Imageworks. The studio first released the $170 million film in both conventional and IMAX 3D theaters on Wednesday, November 10, 2004. It was the last film in which Michael Jeter made a contribution as he had died on March 30, 2003, and the film is dedicated to his memory.
