Tonight, as the six wives of Henry VIII take the stage at the Gran Vía Theatre in Madrid, Madrid will officially celebrate the Spanish-language premiere of SIX. It will be easy to frame its arrival as just another addition to a Madrid lineup increasingly crowded with international musicals. The industrial machinery behind it is far more interesting.
Spain is the first European country to produce a local version of SIX in its own language. Germany, the Netherlands, Italy and even Barcelona had previously hosted the British tour in English. Madrid changes the model: its own cast, local production, and the script fully adapted into Spanish. Producer Julia Gómez Cora also confirms that decision-makers from other European markets will come to Madrid to see how it works before considering their own versions.
That makes the coming weeks resemble a continental-scale commercial tryout. What will be tested at the Gran Vía Theatre is not merely whether SIX works in Spain. The new question is whether the musical can stop traveling in English across Europe and become a franchise rebuilt language by language.
The Gran Vía Theatre has scheduled the official premiere for September 17, after preview performances, and initially keeps the production as a limited-run season.
Madrid changes the model with which SIX had traveled across Europe
SIX’s international expansion has a peculiarity that is easily overlooked when skimming the list of countries where it has been staged.
That the musical has visited a market does not mean that country produced its own version.
The show had already passed through places like Germany, Italy, the Netherlands, or Spain. But the formula used in Europe was basically to export the British production. That was also the case in Barcelona, where the English tour landed in 2025, keeping the show in its original language.
Madrid represents something different.
Julia Gómez Cora, responsible for the Spanish production alongside Stellar Theatre, has explained that Spain is the first European country to stage it locally in its own language. Previously versions had been produced in languages other than English in South Korea and Japan. The producer explained the process and Madrid’s pioneering role in this interview.
The difference is not minor. A tour transports a show already finished from one country to another. A local production requires proving that the product can survive when part of what makes it recognizable is changed.
And in SIX, a large part of that product is precisely the words.
Translating ‘SIX’ means rebuilding a portion of the show
The premise seems simple. Catherine of Aragon, Anne Boleyn, Jane Seymour, Anne of Cleves, Catherine Howard, and Catherine Parr transform into members of a pop band and compete to prove which of them suffered the most during her relationship with Henry VIII.
But SIX does not work solely on that idea.
Its songs blend pop tempo, wordplay, historical references, double meanings, and nods to contemporary artists. Each queen even has a musical persona built from recognizable pop codes.
That makes a word-for-word translation practically useless.
Gómez Cora explains that the Spanish team has been working on the adaptation for more than a year and that the control of the material by Toby Marlow and Lucy Moss, the original creators, is exceptionally tight. Each version must preserve intention, rhythm, humor, and meaning.
The method used proves especially revealing: once the text is adapted into Spanish, it is translated back into English so that the creative team can check exactly what is being said in a language they do not master.
It is not enough to preserve meaning either.
Spanish often requires more words or syllables to express certain ideas than English. At the same time, the music does not allow extra space. The sentence must still fit into the same measure, preserve the rhyme, and produce a similar effect for a different audience.
There are also pop references that automatically work in the United Kingdom and need to be rethought for Spain.
Thus, the task is something far more delicate than translating a script: you must provoke in Madrid a cultural reaction equivalent to that produced by the original while continuing to present the same show.Why European producers will now look to Madrid
Here lies the detail that makes the Madrid premiere an industrial story.
According to Gómez Cora, producers from other European markets, where the English tour had previously played, will come to Madrid to see what happens when SIX is produced locally and in another language. If the adaptation works, some may later study their own versions.
Madrid thus becomes, willingly or not, the first European case study.
This is not about proving there is an audience for SIX. The show has already toured 16 countries, and the Spanish production estimates 3.5 million yearly viewers worldwide.
What had not yet been tested in Europe was something else: whether that success could multiply through national productions that abandon English.
If it happens, the economic logic changes. Instead of circulating a British tour to various cities, SIX could become a replicable property with local casts and crews for potentially longer seasons.
Madrid is the first test.
The paradox of the Madrid musical: importing is better than creating
The experiment also fits a particular characteristic of Madrid’s theatre industry.
The capital has become a hub capable of sustaining technically complex international productions, long seasons, large casts, and a lineup increasingly similar to that of the major Anglo-Saxon markets. But many of its biggest titles still come from intellectual properties developed outside Spain.
SIX belongs to that category. It was created by Toby Marlow and Lucy Moss and began its life at the Edinburgh Festival Fringe before growing on the West End and Broadway.
Madrid did not create the title.
What it is demonstrating is another industrial capability: importing a property, rebuilding it for the Spanish market, and doing so with enough sophistication that other countries observe the process.
It is not the creation of intellectual property, but nor is it mere importation. It is theatrical localization.
And there may be a competitive edge for a market that has spent years accumulating performers, directors, technicians, theatres, and producers accustomed to working with large international licenses.
The production maintains the original structure, but cannot copy everything
The Spanish version is conceived as a replica of the original show.
That means the production has not been given free rein to reinvent set design, dramaturgy, or concept. The aim is to reproduce in Madrid what works in London, but translating it culturally into Spanish.
The official Spanish site for ‘SIX’ keeps the original producers Kenny Wax, Wendy and Andy Barnes and George Stiles, and places Julia Gómez Cora and Stellar Theatre at the helm of the Spanish presentation.
Casting has also been supervised by the original creative team. But there is another room for localization: the performers do not have to become replicas of those who previously portrayed the queens.
Gómez Cora herself explains that each performer’s individual personality is a crucial part of the character, and that the show depends especially on the connection between the six actresses and the audience.
The Spanish edition is led by Clara Lanzani, Udara Zubillaga, Beatriz Santana, Liz Tatis, Arianna Galletti, and Alba Egilo.
The show runs for about 80 minutes, according to Gran Vía Theatre information.
What SIX has at stake during these weeks
The initial performances began before the official September 17 premiere, and the Madrid season is initially planned as limited.
But the relevant metric will not be only how many seats it fills.
The production company has another indicator in mind: the emergence in Spain of the fandom that accompanies the musical in other markets. Audiences who know the songs, follow different performers, and return to the theatre to see different combinations of the queens.
That phenomenon matters because it turns a musical that lasts just over an hour into a product capable of generating repeat attendance.
And beyond that is the metric that cannot be observed from the orchestra pit: what conclusions European producers traveling to Madrid will draw.
If the Spanish version proves that the jokes survive, that the songs work in another language, that a local fandom appears, and that the audience accepts the production as something their own, Spain will have provided SIX with a test it did not yet have in Europe.
It will have shown that the musical can stop being a British export and become a replicable European format.
Madrid has spent years trying to establish itself as one of the great capitals of musical theatre.
In this instance, what is revealing is not that it returns its gaze to London.
It is that London and other European markets have reasons to watch what is happening now in Madrid.
The keys
- SIX officially premieres its first fully Spanish-language version on September 17.
- According to its producer, Spain is the first European market to produce a local version in its own language.
- The adaptation has required more than a year of work, and the Spanish text is retranslated into English so the original creative team can supervise it.
- Producers from other European markets will travel to Madrid to observe how the version operates before weighing up their own productions.
