Netflix’s The Photographer of Mauthausen Brings a Forgotten Holocaust Story to the Screen

Few photographs carry the weight of Francisco Boix’s. Taken inside the Mauthausen concentration camp, they recorded a reality the Nazis were trying to conceal. Years later, those images would help expose what had happened there.

That story is at the center of The Photographer of Mauthausen, a Spanish-language historical drama directed by Mar Targarona and released on Netflix on February 22, 2019. Starring Mario Casas as Boix, the film follows a Spanish Republican prisoner who risked his life to preserve photographic evidence of Nazi crimes.

The result is a grim, often difficult film, but also an important one. Its most powerful idea is simple: when people try to erase the truth, photographs can become evidence that refuses to disappear.

Francisco Boix and the photographs of Mauthausen

Based on a true story, The Photographer of Mauthausen follows Francisco Boix, a Catalan communist who was imprisoned at the Mauthausen concentration camp in Austria after being captured and handed over to the Nazis.

Boix was assigned to the camp’s photography department, where prisoners were forced to document life and death inside Mauthausen. The position gave him access to something most prisoners could never safely reach: photographic negatives showing the camp and the atrocities taking place there.

Rather than allowing the material to disappear, Boix and fellow prisoners secretly removed and concealed thousands of negatives. More than 2,000 negatives were ultimately preserved. The photographs later became important evidence of Nazi crimes and were presented during the Nuremberg proceedings.

The United States Holocaust Memorial Museum’s archives preserve photographs connected to Boix and Mauthausen, including images of forced labor, prisoners, the camp itself, and the aftermath of liberation. The museum also identifies Boix as a concentration-camp survivor who testified at Nuremberg.

That history gives the movie its central tension. Every roll of film represents evidence, but possessing that evidence inside a concentration camp could also mean death.

A deliberately dark portrait of life inside the camp

Mauthausen was one of the largest concentration-camp complexes operated by Nazi Germany. The camp system held hundreds of thousands of prisoners over the course of the war, and tens of thousands died there from forced labor, starvation, disease, abuse, and systematic killing. The U.S. Holocaust Memorial Museum estimates that 197,464 prisoners passed through the Mauthausen concentration camp system between August 1938 and May 1945, with at least 95,000 people killed there.

Targarona does not soften that history.

The nearly two-hour film spends considerable time depicting the exhausting routine imposed on prisoners: brutal labor, inadequate food, humiliation, fear, and the strange performances prisoners were sometimes forced to stage for camp officers.

Rather than rushing from one dramatic event to another, the film often moves at a measured pace. Silence becomes one of Targarona’s most effective tools. Music is used sparingly but deliberately, intensifying moments that might otherwise be almost unbearable to watch.

That restraint makes the violence feel even more oppressive. The movie understands that the horror of Mauthausen was not confined to individual acts of cruelty. It was built into the prisoners’ everyday existence.

Mario Casas gives the story its human center

Mario Casas carries much of the film as Boix, giving the character an energy that prevents the story from becoming relentlessly bleak.

Boix retains a sense of humor even in circumstances where humor seems almost impossible. Those brief moments of lightness provide some relief without undermining the seriousness of the story.

Casas also underwent a major physical transformation for the role, losing 40 pounds to portray a concentration-camp prisoner.

The supporting cast is less distinctive, although Richard Van Weyden makes a strong impression as S.S. officer and camp photographer Paul Ricken, whose relationship with photography becomes one of the film’s most disturbing elements.

When the perpetrators became the photographers

One of the film’s most interesting choices is its attention to the Nazi obsession with documenting their own crimes.

Holocaust films often center primarily on the experiences of prisoners. The Photographer of Mauthausen also asks why the perpetrators themselves created such an extensive photographic record.

Ricken’s photographs reveal a particularly disturbing relationship with death. He is portrayed as rearranging prisoners and their surroundings to produce more striking images, treating suffering as something to be composed and observed.

The film also explores the idea that a photograph does not necessarily represent an objective reality. It records a particular point of view.

That concept takes on an extraordinary irony in the story of Boix. Images created within the Nazi system to document life at Mauthausen eventually helped expose the system itself.

Photographs were presented as evidence during the International Military Tribunal at Nuremberg, which formally opened on November 20, 1945. The surviving images became part of the broader body of evidence used to document Nazi crimes.

Boix himself testified at Nuremberg. The Holocaust Museum’s archival record includes footage of him identifying Albert Speer and describing how photographs taken at Mauthausen documented visits by senior Nazi figures.

A story centered on Spanish prisoners

Another distinctive aspect of The Photographer of Mauthausen is its focus on Spanish Republican prisoners.

That perspective reflects Boix’s own background. After the Spanish Civil War, thousands of Spanish Republicans ended up in Nazi concentration camps. Mauthausen became particularly associated with their imprisonment.

According to the film’s original account, Spanish Republicans represented 60 percent of Mauthausen’s prisoners by 1941. The story therefore offers a perspective that differs from many Holocaust dramas, which tend to concentrate primarily on Jewish victims.

The focus does not diminish the broader history of Nazi persecution. Instead, it shows how the regime targeted political opponents and other people it considered threats, alongside its systematic persecution and murder of Jews and other groups.

A beautiful film about an ugly history

Visually, The Photographer of Mauthausen avoids one familiar convention of historical dramas: deliberately making the movie look old.

Targarona has argued against the idea that a period film needs to be grainy or drained of color to look historical. The film consequently maintains a comparatively polished visual style rather than relying on an artificial aged appearance.

That choice works in its favor. The cinematography is striking without constantly calling attention to itself, and the images of Mauthausen feel immediate rather than filtered through a deliberately antiquated aesthetic.

The result is a film that can be visually accessible even while telling an exceptionally grim story.

The subtitles can be challenging

The movie does have a significant weakness, particularly for American viewers.

Much of the dialogue is in Spanish, with German also appearing at times, and the characters often speak quickly. Following the subtitles can therefore become difficult, especially during scenes with several characters talking or when the story is moving rapidly.

The film also assumes a certain familiarity with Mauthausen and its history. For viewers who know little about the camp, some events and references may have less immediate context.

That is an understandable consequence of a Spanish production telling a story rooted deeply in Spain’s own wartime and postwar history. It can also serve as an invitation to look beyond the movie and learn more about Mauthausen itself.

The historical record makes clear how important the camp was within the Nazi concentration-camp system. The U.S. Holocaust Memorial Museum’s collection contains extensive photographic evidence of the camp, its personnel, forced labor, prisoners, and liberation.

Why Boix’s photographs still matter

The strongest reason to watch The Photographer of Mauthausen is ultimately not its performances or cinematography. It is the story behind the photographs.

Boix understood that the Nazis’ own documentation could become evidence against them. By helping preserve approximately 2,000 negatives, he and other prisoners ensured that photographs intended to serve the camp’s machinery of documentation could survive beyond it.

That makes photography the film’s central moral idea. An image can be manipulated. It can reflect the perspective of the person holding the camera. But when enough evidence survives, it can also make denial considerably harder.

The historical record bears that out. The Holocaust Museum’s collections describe photographs as important documentation of Nazi crimes, while its Nuremberg archives show how photographs, documents, and other physical evidence were presented during the trials.

For a story about people trying to destroy evidence, that survival is extraordinary.

An essential, difficult watch

The Photographer of Mauthausen is not an easy film. Its subject matter is brutal, its pacing can be slow, and the subtitles may require concentration.

But those difficulties are outweighed by the importance of the story.

The film arrived at a time when Holocaust denial and antisemitism remained serious concerns in the United States. The original review also cited 2018 survey findings reporting that 11 percent of Americans were not familiar with the Holocaust and a separate finding that only 45 percent could name a Nazi-controlled concentration camp.

That context makes Boix’s story especially resonant. Historical truth can be challenged, forgotten, or distorted. The photographs he helped save provide something harder to dismiss: a physical record of what happened.

The U.S. Holocaust Memorial Museum’s archives preserve many of those photographs and related materials today. They offer a reminder that documentation was itself part of the struggle against Nazi crimes.

The Photographer of Mauthausen ultimately works as both a Holocaust drama and a tribute to the power of photographic evidence. Francisco Boix was imprisoned, threatened, and surrounded by people determined to control the historical record. Yet the images survived.

And decades later, his photographs still speak for those who were not able to tell their own stories.
