The Unthinkable Daughter: Netflix lets Suzane von Richthofen speak after three films spoke for her

For more than twenty years, Brazil has known Suzane von Richthofen as a picture rather than a voice: a courtroom photograph, a magazine cover, two actresses wearing her name on streaming services. Netflix‘s The Unthinkable Daughter changes the format. The Brazilian true-crime documentary is built on new, exclusive interviews with the woman convicted of planning the murder of her parents, her first interview in more than a decade, and it arrives on Netflix as a feature-length film directed by Lygia M. Barbosa and Paulo Gambale Maká.

The case behind it needs little introduction in Brazil and a short one everywhere else. Manfred and Marísia von Richthofen were killed in the family home in Brooklin, a residential district of São Paulo, by the brothers Daniel and Cristian Cravinhos. Daniel was Suzane’s boyfriend. She was convicted of planning the killings with them, and for most of her adult life she has been one of the most recognisable prisoners in the country.

In the trailer, she offers one sentence of her own: “I am not the monster people hear about.” Netflix’s own description of the film is more careful than the line. The documentary, the platform says, looks at who Suzane became after serving part of her sentence and confronts her with what was investigated and established in the case. Archive footage, experts and people connected to the case complete the film. That second clause matters. A documentary that only recorded her account would be a platform for it; one that sets her account against the record is doing something closer to journalism, at least on paper.

Barbosa has been explicit that the killing is not the only subject. “The documentary allows us to discuss issues that are very dear to our society, such as the media and its impact on this and other similar cases, resocialisation, and a little of the reality of the penal system in Brazil,” she said in the announcement published by Netflix. Netflix tags the title “Media Circus” on its own page. The film appears to know that it is entering a story the media has been telling for a long time, and that it is one more teller.

The fourth screen version of one night

That is the context an international viewer is likely to miss. The Unthinkable Daughter is not the first screen version of this case. It is roughly the fourth. Two fiction features arrived on Prime Video together: The Girl Who Killed Her Parents and The Boy Who Killed My Parents, each staging the same night from a different defendant’s version, one from Daniel Cravinhos’ account and one from Suzane’s. Carla Diaz played Suzane in both. A third film, The Girl Who Killed Her Parents: The Confession, followed. Then the series Tremembé, based on a book about the prison in São Paulo state known for holding famous inmates, cast Marina Ruy Barbosa in the role.

Each of those productions added a face to the name. None of them gave the name a voice of its own, because the person was not involved. That is the real novelty of the Netflix film and also its risk. The premise suggests a correction: after a series of actresses, the original. But an interview is also a performance with its own lighting, its own edit and its own interests, and the people watching it have spent two decades being taught how to read this particular face.

The titles Netflix chose for different markets show how much framing happens before a single frame plays. In Brazil the film is called Suzane von Richthofen: O que o Tempo Não Apaga, roughly “what time does not erase”. In France it is La Fille indigne, the unworthy daughter. The Turkish title promises “an unthinkable betrayal”; the Korean one names “the sin time cannot erase”. The English title, The Unthinkable Daughter, places the weight on her role in the family rather than on the crime. Same film, many verdicts in the packaging.

Who appears, and who was paid

Alongside Suzane, the documentary features her husband, the physician Felipe Zecchini Muniz, and the criminal profiler and author Ilana Casoy, who has written about the case and co-wrote the screenplays of the 2021 fiction films. The remaining voices are described only as experts and people connected to the case; Netflix has not published a full list.

The arrangement behind the interview has already drawn scrutiny at home. Brazilian press reported that Suzane received about R$500,000, the equivalent of 308 monthly minimum wages, and that her husband was paid an undisclosed amount for image rights. The same reports describe a lifelong confidentiality clause covering the deal. The reported fee sits awkwardly next to a film that wants to talk about how the media profits from cases like this one.

The project also reached the public sideways. Netflix confirmed it only after footage from an invitation-only preview leaked online, when the film still carried the working title Suzane Vai Falar, “Suzane Will Speak”. Reports from that preview said she describes her childhood, a difficult relationship with her parents, and the birth of her son, after which she says she felt forgiven by God. The finished film, retitled for a global release, is the version that counts; the leak simply means some of its material has been argued over for months already.

A film about resocialisation, in a country still arguing about it

Suzane now serves the rest of her sentence outside prison under Brazil’s open regime, the last stage of a progressive system meant to return convicted people to ordinary life. That is the thread Barbosa calls resocialisation, and the documentary’s description promises experts on the penal system as part of it. Brazilian coverage of the trailer has already folded in the familiar questions: the limits of turning real cases into entertainment, the right to be forgotten, the pain of the victims’ relatives, and the line between public interest and exploiting a tragedy.

Another excerpt quoted in the Brazilian press cuts against the “monster” line. “I could have stopped, but I didn’t stop. I couldn’t stop,” she says, an admission that sits closer to the court’s finding than to a denial. How the film arranges those two sentences, one defensive and one confessional, will decide what kind of documentary it is.

The Unthinkable Daughter enters a Netflix shelf that already includes Elize Matsunaga: Once Upon a Crime, another Brazilian case told through the convicted woman’s own interviews. The format has a known appeal and a known weakness. Access to the subject is the selling point, and access always comes with terms.

What none of these productions can settle is whether Suzane von Richthofen can still be heard as a person rather than read as an image. The courts reached their verdict long ago. The documentary can set her words against the case file and the coverage. It cannot decide whether a paid interview, cut by others, is her voice at last or simply the newest frame around the same picture.
