Jennifer Lee wrote the book for the stage musical, while Kristen Anderson-Lopez and Robert Lopez wrote its music and lyrics. The show adapts Disney’s 2013 animated film, keeping familiar songs and adding new ones for the stage.
Those credits can be confusing because “writer” may mean the person who wrote the dialogue and story, or the people who created the songs. Here’s who handled each part, what their work involved, and how the stage version builds on the film without simply copying it.
who wrote frozen the musical?
Jennifer Lee wrote the book—the dialogue and dramatic structure—while Kristen Anderson-Lopez and Robert Lopez wrote the music and lyrics. The stage production is based on Disney’s 2013 film, and the three writers’ roles reflect the different parts of a musical: its script, songs, and score.
So, the answer depends on what you mean by “wrote.” If you mean the person responsible for the stage script, the answer is Lee. If you mean the songwriters, it is the husband-and-wife team Kristen Anderson-Lopez and Robert Lopez. Together, their work adapts the film’s story for a live theater audience.
What each writer contributed
A musical has several creative parts, and the people credited as writers do not all do the same job. Knowing the difference helps you identify who wrote the dialogue, who created the songs, and who shaped the way the story unfolds onstage.
| Writer | Role | What that means |
|---|---|---|
| Jennifer Lee | Book writer | Wrote the stage script, including dialogue and the structure linking scenes and songs. |
| Kristen Anderson-Lopez | Music and lyrics | Co-wrote the show’s songs, working with Robert Lopez on words and music. |
| Robert Lopez | Music and lyrics | Co-wrote the show’s songs with Kristen Anderson-Lopez. |
Jennifer Lee wrote the book
In theater, the book is the spoken script and the framework of the story. It includes dialogue, scenes, and the dramatic choices that connect one song to the next. It is not a printed program or a collection of lyrics.
Lee brought direct knowledge of the film’s story and characters to the stage adaptation. Her task was to make the plot work in a live performance, where scenes need to play clearly in front of an audience and transitions must support the action happening onstage.
Kristen Anderson-Lopez and Robert Lopez wrote the songs
The Lopezes wrote the music and lyrics for the stage musical. Music refers to the melody and musical composition; lyrics are the words sung by the characters. Their contribution includes songs familiar from the movie and numbers written for the theater version.
Songwriters help reveal what characters want, fear, or decide. A song can carry a feeling or conflict further than ordinary dialogue, while also giving performers a chance to express the story through music. In a stage show, songs need to work as part of the live drama, not just as stand-alone recordings.
How the stage musical connects to the film
The Broadway musical is an adaptation of Disney’s animated film Frozen, released in 2013. It follows the central relationship between sisters Anna and Elsa and the conflict surrounding Elsa’s powers. The stage version preserves the recognizable story and several songs audiences know from the movie, but it also adds material created for live theater.
An adaptation does not have to reproduce every moment in precisely the same way. Film can move quickly between locations and use animation to show a character’s surroundings or powers. A stage production must create those moments live, using performers, scenery, lighting, costumes, sound, and theatrical effects. The writing has to support that different way of telling the story.
The musical also gives the characters more opportunities to sing. That can make a character’s feelings or decisions clearer, or add a scene that helps the story make sense in a theater setting. Even when a song or plot point is familiar, its placement and effect may differ from the film.
Which songs did the writers create?
The stage version includes well-known songs from the film, such as “Let It Go,” “Do You Want to Build a Snowman?” and “For the First Time in Forever.” It also features songs written for the stage production. One notable new number is “Monster,” which gives Elsa a different musical moment as she wrestles with the consequences of her powers.
Other stage additions include “Hygge,” “What Do You Know About Love?” and “Dangerous to Dream.” These songs help expand the show beyond the film’s soundtrack. They give the characters additional chances to express their thoughts and help shape the pacing of the stage story.
The exact song list can vary by production, and a performance may differ from the original Broadway staging. If you are checking a specific tour, school, or regional production, use that production’s program or official listing for its current song order.
Why does the musical have more than one writer?
A stage musical combines spoken scenes with songs, so it usually involves distinct writing roles. One writer may focus on the book, while songwriters create the music and lyrics. Those people work together so the dialogue, songs, characters, and plot feel like parts of the same show.
For this production, Lee’s book and the Lopezes’ songs serve different but connected purposes. The book establishes what is happening and what characters say. The songs can deepen a conflict, show a change in perspective, or provide a musical expression of an idea that the dialogue has introduced.
That division does not mean the writers worked in isolation. A song needs to fit the scene around it, and the scene needs to make room for the song’s dramatic purpose. The result is a performance in which story and music are designed to support one another.
Who else helped create the Broadway production?
Writers are not the only artists who shape a musical. A director guides the overall staging and performance; choreographers create movement and dance; designers build the production’s visual and sound world. Actors, musicians, stage managers, and production teams also bring the show to life.
For the original Broadway production, Michael Grandage directed, and Rob Ashford choreographed. Those are important creative credits, but they do not replace the writing credits. Grandage’s direction shaped the production’s staging, while Ashford’s choreography shaped its movement. Lee and the Lopezes remain the credited writers of the book, music, and lyrics.
This distinction is useful when you are looking at a theater program or cast listing. A director may be credited as a leading creative artist, but that does not mean the director wrote the script or songs. Check the specific credit—book, music, lyrics, direction, or choreography—to see what each person did.
How to read the show’s writing credits
Programs and listings may use theater terms that sound similar. Here is a simple way to read the main writing credits:
- Book: the script, dialogue, and structure of the scenes.
- Music: the melodies and musical composition.
- Lyrics: the words sung in the songs.
- Based on: the earlier work that provided the source material, in this case the Disney film.
One person can hold more than one writing role, but that is not the arrangement here. Lee is credited with the book, and Kristen Anderson-Lopez and Robert Lopez are credited with music and lyrics. The source film provides the story foundation, while the stage adaptation turns it into a live musical.
Is the stage musical exactly the same as the movie?
No. It adapts the same central story and includes familiar songs, but the stage version has additional songs and theater-specific choices. Live performance also uses different tools from animation, so the staging, pacing, and way certain scenes are presented can differ.
That difference is normal for an adaptation. A theater audience watches performers share a physical space, and the production must make the story readable from the auditorium. The script and score therefore need to work with live acting, choreography, scenery, lighting, and effects.
What people often get wrong about the writers
A common mix-up is to credit only the Lopezes because their songs are among the best-known parts of Frozen. They wrote the music and lyrics, but Jennifer Lee wrote the book for the stage musical. If the question is about who wrote the spoken script, naming only the songwriters leaves out the book writer.
The reverse mistake is to say Lee wrote all the songs. Her role as book writer is separate from the Lopezes’ music-and-lyrics credit. The clearest short answer is therefore: Jennifer Lee wrote the book; Kristen Anderson-Lopez and Robert Lopez wrote the music and lyrics.
Another detail readers sometimes miss is that the stage musical’s credits should not be confused with the credits for the original movie. A film and its stage adaptation can share a story and songs while having distinct production credits and creative responsibilities.
Quick answer for a program, report, or trivia question
If you need a concise answer, write: “The stage musical’s book was written by Jennifer Lee, and its music and lyrics were written by Kristen Anderson-Lopez and Robert Lopez.” That wording identifies all three writers and makes their roles clear.
If the question asks only who wrote the songs, answer Kristen Anderson-Lopez and Robert Lopez. If it asks who wrote the book, answer Jennifer Lee. This small distinction avoids the most common crediting error and gives a more complete answer than naming just one writer.
Jennifer Lee wrote the book for the stage adaptation, while Kristen Anderson-Lopez and Robert Lopez created its music and lyrics. Their separate roles explain why the musical has both a script writer and songwriters.
For a quick reference, match the credit to the question: Lee for the book, and the Lopezes for the songs. If you are citing a particular production, check its program for any production-specific credits or changes.
