Tom Hanks voices several of The Polar Express’s most recognizable characters, including the Conductor, the Hobo, the Boy’s Father, Scrooge, and Santa Claus. However, the principal voice performer credited for Hero Boy is Daryl Sabara. Other characters—including Hero Girl, Billy, Sister Sarah, and Smokey and Steamer—also have layered credits involving principal performers, voice performers, and additional child performers.
That distinction is important because cast databases do not always organize The Polar Express credits the same way. The following guide uses the film’s AFI Catalog credit categories as its baseline, separating principal cast, voice performers, additional child performers, and ensemble contributors.

The Polar Express was released in the United States on November 10, 2004. It is a 99-minute, English-language, G-rated animated feature directed by Robert Zemeckis and distributed by Warner Bros. Pictures. The film adapts Chris Van Allsburg’s 1985 picture book.
Who does Tom Hanks play in The Polar Express?
Tom Hanks has an unusually broad role list in the film. The primary cast credit assigns him six named roles:
#1 Best Overall
- Hero Boy
- Father
- The Conductor
- The Hobo
- Scrooge
- Santa Claus
The Conductor is Hanks’s most prominent adult character in the story. He welcomes the children aboard the train, manages the journey to the North Pole, and acts as the authoritative guide through the film’s strange and often dangerous events. Hanks also plays the mysterious Hobo, the Boy’s Father, the dramatic Scrooge figure in the Christmas show, and Santa Claus.
Hero Boy requires more careful wording. Hanks is also credited as Hero Boy, but AFI separately identifies Daryl Sabara as the principal voice performer and Josh Hutcherson as an additional child performer. It is therefore inaccurate to describe Hanks as the sole voice of Hero Boy or Hutcherson as the character’s sole voice.
Daryl Sabara as Hero Boy
Daryl Sabara is specifically listed among the film’s voice performers as Hero Boy. The character is the unnamed central child whose growing uncertainty about Santa Claus drives the story. Tom Hanks is also included in the primary cast credit for Hero Boy, while Josh Hutcherson appears in the additional child-performer category.

Performance-capture animation can involve different contributors for a character’s physical performance, facial or child-performance work, and final voice. The credit categories indicate that Hero Boy’s portrayal was shared rather than attributable to one performer in every respect.
Nona Gaye as Hero Girl
Nona Gaye receives the principal cast credit for Hero Girl, the confident passenger who joins Hero Boy on the train. Chantel Valdivieso is separately credited as an additional child performer.
Rank #2
- Factory sealed DVD
Some commercial databases refer to this character as “Holly.” The film-credit wording used by AFI is Hero Girl, so that is the safest primary name for a cast guide. “Holly” can be mentioned as an alternate database identification, but it should not be presented as an unequivocally confirmed on-screen credit name.
Billy, the Lonely Boy
The character commonly known as Billy is identified in the credits as the Lonely Boy. His performance has three relevant layers:

- Jimmy Bennett is listed as a voice performer for Lonely Boy.
- Hayden McFarland is credited as an additional child performer.
For that reason, the most precise answer is not simply “Jimmy Bennett voices Billy” or “Peter Scolari voices Billy.” Both names appear in distinct parts of the film’s credit structure, with McFarland also contributing child-performance work.
The other named characters
Eddie Deezen as Know-It-All
Eddie Deezen is the principal credited voice performer for Know-It-All, the fast-talking child passenger whose constant interruptions provide comic relief. Jimmy “Jax” Pinchak is credited as an additional child performer.
Leslie Zemeckis as Mother and Sister Sarah
Leslie Zemeckis is credited as both the Boy’s Mother and Sister Sarah. Sister Sarah also has two additional credit layers: Isabella Peregrina is listed as a voice performer, and Ashly Holloway is credited as an additional child performer.

Michael Jeter and André Sogliuzzo as Smokey and Steamer
Michael Jeter receives the prominent cast credit for the railroad workers Smokey and Steamer. André Sogliuzzo is separately identified as a voice performer for the pair. This is a distinction in the credit categories, not simply a duplicate database entry.

Chris Coppola as Toothless Boy
Chris Coppola is credited as Toothless Boy/Elf, while Connor Matheus is listed as an additional child performer for Toothless. Some listings shorten the character name to “Toothless”; the fuller film-credit wording is Toothless Boy.
Julene Renee, Charles Fleischer, and Steven Tyler
- Julene Renee plays Red-Head Girl/Elf.
- Charles Fleischer plays Elf General.
- Steven Tyler plays Elf Lieutenant and Elf Singer.
Why do some characters have more than one performer?
The film’s credits distinguish among several kinds of contribution:
- Principal cast credits: the prominent performer-role listings normally used by general cast guides.
- Voice performers: contributors specifically identified for voice work.
- Additional child performers: child performers whose work formed part of a character’s overall animated performance.
- Performance-capture and acrobatic-elf contributors: performers credited for physical or ensemble work rather than necessarily for a character’s final spoken voice.
Because The Polar Express was made using performance-capture techniques, a single screen character could involve more than one credited contributor. A cast list that collapses all of these categories into a single “voice actor” field can make the credits appear inconsistent when they are actually describing different jobs.
Supporting and ensemble cast
AFI also credits the following supporting performers:
Pastry chefs
- Brendan King
- Andy Pellick
Waiters
- Josh Eli
- Mark Mendonca
- Rolandas Hendricks
- Mark Goodman
- Jon Scott
- Gregory Gast
- Sean Scott
- Gordon Hart
Elves
- Phil Fondacaro
- Debbie Lee Carrington
- Mark Povinelli
- Ed Gale
Dante Pastula is credited as Little Boy.
The broader performance-capture and acrobatic-elf credits include Eric Newton, Aidan O’Shea, Aaron Hendry, Kevin C. Carr, Bee Jay Joyer, Jena Carpenter, Karine Mauffrey, Beth Carpenter, Bill Forchion, Devin Henderson, and Sagiv Ben-Binyamin. These contributors belong in a full-credit listing, but they should not be presented as the principal voice cast unless the article clearly labels their specific performance or ensemble roles.

The Polar Express is based on Chris Van Allsburg’s 1985 picture book, which won the Caldecott Medal. The movie expands the short illustrated story into a feature-length journey while retaining its central premise: a doubting child boards a magical train bound for the North Pole.
The soundtrack
Alan Silvestri composed the film’s music. The motion-picture soundtrack is a 14-song release issued by Reprise Records in the United States on November 2, 2004. It is a useful companion for collectors and fans of the movie’s music, although physical CD availability may vary by retailer and date.
See the story beyond the screen
Some railroads host an officially licensed Polar Express Train Ride experience during the holiday season. Rail Events identifies these events as licensed on behalf of Warner Bros., while individual host railroads handle local dates, locations, tickets, and operations. Availability is therefore location-specific and seasonal; verify the venue, year, ticket terms, and licensing details before making plans.

Frequently Asked Questions
Is Tom Hanks the voice of Hero Boy in The Polar Express?
Tom Hanks is credited as Hero Boy, but he is not the only performer associated with the character. AFI lists Daryl Sabara as the principal voice performer and Josh Hutcherson as an additional child performer. The most accurate description is that Hero Boy has a layered performance credit.
Who voices the Conductor in The Polar Express?
Tom Hanks voices and performs the Conductor. Hanks also plays Hero Boy, the Hobo, the Boy’s Father, Scrooge, and Santa Claus.
Who plays Billy in The Polar Express?
Billy is identified in the credits as the Lonely Boy. Peter Scolari has the principal credited performer listing, Jimmy Bennett is credited as a voice performer, and Hayden McFarland is credited as an additional child performer.
Is Hero Girl called Holly in The Polar Express?
Some commercial databases call Hero Girl “Holly,” but the AFI film-credit wording is “Hero Girl.” That is the safer primary name to use when describing the movie’s cast.
The Bottom Line
The short answer: Tom Hanks plays the Conductor and five other credited roles, but Daryl Sabara is the principal voice performer for Hero Boy. Nona Gaye plays Hero Girl, Eddie Deezen plays Know-It-All, Leslie Zemeckis plays Mother and Sister Sarah, and Michael Jeter is prominently credited as Smokey and Steamer. Multiple names attached to several characters reflect the film’s performance-capture and separate voice-credit categories—not necessarily conflicting cast lists.
