The Polar Express is Robert Zemeckis’s 2004 American animated Christmas film adapted from Chris Van Allsburg’s 1985 picture book, depicting a young boy on Christmas Eve who is uncertain about his belief in Santa Claus and is swept aboard a steam train bound for the North Pole. Tom Hanks performs motion capture for six different roles including the boy, the conductor, the boy’s father, the hobo, the narrator, and Santa Claus. Daryl Sabara provides the boy’s speaking voice. Eddie Deezen voices Know-It-All. The screenplay was written by Robert Zemeckis and William Broyles Jr. Warner Bros. released the film in November 2004 in standard and IMAX 3D presentations. The Polar Express was the first feature film produced entirely with performance-capture animation.
The film’s central technological achievement and its central technological problem are the same thing. Zemeckis spent five years developing the motion-capture process that allowed Hanks to perform multiple roles simultaneously, with each character built from Hanks’s facial and body movements. The technology produced unprecedented control over animated character movement and produced what critics and audiences quickly identified as the uncanny valley problem: human characters with movement and proportions just realistic enough to register as not-quite-right. The technical innovation and the audience-reception problem have run parallel ever since, with the film’s reputation balanced precariously between technical landmark and visual unease.
Tom Hanks’s Multiple Performances
Hanks performed all six roles through motion capture, with his physical movement and facial expression mapped onto the digitally rendered characters. The conductor and the hobo are recognizably Hanks. The boy and Santa Claus are recognizably Hanks under additional design layers. The technical accomplishment is substantial and shows Hanks’s range as a physical performer rather than only a vocal one.
Hanks’s commitment to the project carried the production through multiple delays and budget overruns. He had collaborated with Zemeckis on Forrest Gump and Cast Away and accepted the multi-role assignment partly as a technical challenge and partly as a Christmas-tradition family project. His performances are uniformly strong. The animation rendering around them is the variable.
For Writers
Performance-capture technology shifts the actor’s craft toward physical embodiment rather than only vocal performance. Hanks’s commitment to physical character distinction across six roles produced six recognizably different performances even before the visual rendering applied.
The Uncanny Valley Problem
The Polar Express became the canonical example of uncanny-valley response in animated film. The boy’s facial expressions read as oddly dead. The eye animation lacks the small involuntary movements that real human eyes carry. The skin rendering has a waxy quality that resists empathic identification. Audiences reported that the film’s protagonist registered as unsettling rather than appealing, particularly in close-up shots.
The technology has improved substantially since 2004, partly through lessons learned from the Polar Express’s reception. Subsequent performance-capture features including Beowulf, A Christmas Carol, and the Avatar series have addressed eye and skin rendering with the explicit aim of avoiding the Polar Express’s reception problem. The 2004 film consequently exists as both technical landmark and cautionary lesson.
For Writers
Technical innovations in animation interact with audience expectations in ways that can produce unexpected rejection. The uncanny-valley reception of Polar Express has reshaped subsequent performance-capture rendering choices across the industry.
The Source Book Question
Van Allsburg’s 1985 source book is a brief picture book with sparse text and watercolor illustrations of considerable beauty. The book’s emotional structure does not naturally extend to a hundred-minute feature film. The screenplay required considerable invention to fill the running time: the train sequences in the snowy mountains, the hot chocolate musical number, the troubled boy hobo, the children who lose tickets, the third-act foundry sequence. Each invention represents the screenplay’s attempt to extend a brief original story.
The hot chocolate sequence is the production’s most ambitious choreographed musical number and the most successful expansion from source. The bell-ringing and silver-bell-on-Santa’s-sleigh material at the climax follows the book’s actual emotional structure. The space between the openings and the endings is the screenplay’s invented territory, and the inventions vary in quality.
For Writers
Adapting short source books to feature length requires invented material that the screenplay must justify on its own terms. The Polar Express’s screenplay successes and failures both come from this expansion problem.
Craft Note
Zemeckis founded ImageMovers Digital partly to continue the performance-capture work begun on Polar Express. The studio produced Beowulf, A Christmas Carol, Mars Needs Moms, and the failed Yellow Submarine project before Disney closed it in 2011. Polar Express grossed over three hundred million dollars worldwide and has become an annual television-broadcast staple. The film’s IMAX 3D release was technically innovative and audience response to the format helped justify subsequent IMAX 3D expansion across exhibition.
Verdict
The Polar Express divides audiences along uncanny-valley response lines. Viewers who can accept the visual register find the film a serviceable family Christmas production with strong Tom Hanks performances and an effective Alan Silvestri score. Viewers who cannot accept the rendering find the film genuinely off-putting. Both responses are valid. The film deserves a careful first viewing before committing to annual rotation.
FAQ
Who directed The Polar Express?
Robert Zemeckis directed the film and co-wrote the screenplay with William Broyles Jr. Zemeckis also directed Forrest Gump, Cast Away, and the Back to the Future trilogy.
How many roles does Tom Hanks play?
Hanks performed six roles: the boy, the conductor, the boy’s father, the hobo, the narrator, and Santa Claus. All six characters were built from Hanks’s motion-capture performances.
What is the uncanny valley?
The uncanny valley is the perceptual phenomenon where human or near-human figures with not-quite-realistic features produce stronger negative response than figures with clearly non-human features. The Polar Express became the classic animated-film example of uncanny-valley response.
Is The Polar Express based on a book?
Yes. The film adapts Chris Van Allsburg’s 1985 picture book of the same title. Van Allsburg also wrote Jumanji and The Stranger.
How did The Polar Express perform commercially?
The film grossed over three hundred million dollars worldwide on a production budget of approximately one hundred sixty-five million. Annual television broadcasts have substantially extended the film’s audience since 2004.
Was The Polar Express the first performance-capture feature?
Yes. The Polar Express was the first feature film produced entirely with performance-capture animation. Earlier films had used the technique for individual sequences or characters.
What is the film’s rating?
The Polar Express is rated G.
