Netflix has released the official A Child of My Own trailer on its YouTube channel, giving audiences their first extended look at the streamer’s newest true-crime documentary hybrid from Oscar-nominated Chilean director Maite Alberdi.
Below is a full breakdown of what’s confirmed, what critics who saw it early are saying, and how the film’s unusual blend of documentary and dramatization has already stirred debate.
The Trailer and Where to Watch It
The official “A Child Of My Own” trailer is live on the Netflix YouTube channel, described with the line: “Alejandra wanted to be a mother more than anything in the world, but she couldn’t.”
Trade coverage of the A Child Of My Own trailer drop came quickly from The Playlist, whose piece frames the film as an examination of a pregnancy lie that snowballed into a national scandal. The listing also surfaced on TheFutonCritic.com, which tracks official network and streamer video releases.
Release Date and Distribution
According to Deadline, Netflix has set August 13 as the film’s streaming debut. Deadline’s reporting notes the documentary will also get a limited theatrical release in the U.S., UK, and Mexico alongside its Netflix drop. Ahead of that date, the film made the festival rounds extensively — a world premiere at the Berlin Film Festival in February, followed by screenings at Visions du Réel in Switzerland, the Buenos Aires International Film Festival, the Doc10 festival in Chicago, and the San Francisco International Film Festival.
What The Film Is About: The Real Case
A Child of My Own is a documentary-fiction hybrid built around a real Mexican case that made national headlines. Per Deadline’s exclusive reporting, the film centers on Eleonor Alejandra Marín Mendoza — known as “Ale” — a hospital nurse who, after suffering repeated miscarriages and facing intense pressure from her husband Arturo and in-laws to produce a child, faked an entire pregnancy for roughly nine months.
The undisputed facts, as laid out by Deadline: in 2008 Ale convinced her husband and family she was pregnant, and in June 2009 she left the Hospital General de México — where she worked — carrying a newborn girl concealed in a bag. What remains disputed is how she obtained that child. Ale has maintained she struck an informal arrangement with a young pregnant woman, Mayra, who didn’t want to keep her baby.
Mayra, whom Alberdi also interviewed, has consistently denied any such agreement, insisting the baby was taken from her without consent — meaning the film essentially stages two competing versions of the same story and leaves audiences to weigh them. Deadline further reports that Ale was ultimately convicted; several reviews note she was sentenced to over a decade in prison, while Arturo was released after roughly two years without formal charges.
Behind the Camera: Maite Alberdi’s Approach
Alberdi is a two-time Oscar nominee, previously recognized for The Mole Agent and The Eternal Memory, and her Netflix relationship also produced the scripted series A Man on the Inside (adapted from The Mole Agent) and the 2024 fiction feature In Her Place. Speaking to Deadline about how she found the story, Alberdi explained she met Ale years ago while researching an unrelated project inside a Mexican jail, and was struck enough by her account to pursue a film.
Rather than a conventional talking-heads true-crime doc, Alberdi shot extensive dramatized reenactments — casting Ana Celeste Montalvo Peña as Ale and Armando Espitia as Arturo — interwoven with real interviews, archival news footage, and surveillance video of the actual events. Deadline quotes Alberdi describing the reenactments as less like fiction and more like a recreation of Ale’s own point of view, a choice she says was a reaction to how one-dimensionally Mexican tabloid media had portrayed Ale as simply “a baby thief.”
The full cast, per The Playlist, includes Ana Celeste Montalvo Peña, Luisa Guzmán, Armando Espitia, Mayra Sérbulo, Casio Figueroa, Alejandro Porter, Mayra Batalla, and Ángeles Cruz, with a script credited to Julián Loyola and Esteban Student. The film runs approximately 96 minutes and was produced by Mexico City-based Gato Grande for Netflix.
Critical Reception So Far
Reviews out of Berlin have been mixed-to-positive, generally praising Alberdi’s craft while raising questions about the film’s point of view.
- The Hollywood Reporter calls it a film that continues to blur fact and fiction, describing it as alternately comical and moving, and credits Alberdi’s “deft narrative footwork” in keeping the reenactments from feeling like tacky made-for-TV reconstructions.
- Variety is more critical of the film’s structure, arguing that its candy-colored, semi-comic framing of Ale’s account occasionally rankles, and suggesting a straighter documentary approach might have served the material better — while also noting the film plays almost like an ironic in-joke given how closely it echoes Netflix’s own true-crime house style.
- Screen Daily highlights the contrast between the glossy, stylized dramatizations and the “crackling, shaky” real archival and CCTV footage, and frames the story within the broader theme of social pressure on women in Latin America to become mothers.
- ScreenAnarchy describes the film’s constant shifting between real and reenacted, past and present, as deliberately disorienting — arguing it ultimately illuminates rather than obscures, and that the film subverts true-crime genre expectations by suggesting Ale needed help rather than simple condemnation.
- Micropsia Cine frames the film almost as a fairy tale, noting its surprisingly warm tone for subject matter that could easily have been sold as dark true crime.
- Aggregated critic and audience blurbs are collected on Rotten Tomatoes, where several reviewers describe the film as a thoughtful meditation on longing, identity, and societal expectations that resists easy judgment.
The Controversy: Whose Story Is This?
Not everyone is on board with the film’s empathetic framing of Ale. On Letterboxd, early viewer reactions include pointed criticism that the documentary risks portraying a convicted baby abductor sympathetically, with some reviewers arguing the mother whose newborn was taken doesn’t get equal narrative weight — a criticism Variety’s review echoes, noting that “Mayra’s real-life counterpart” and other dissenting perspectives get comparatively “shorter shrift” in service of preserving the film’s central mystery.
This tension — between humanizing Ale’s psychological unraveling and doing justice to the woman who says her baby was effectively stolen — is likely to be the central talking point once the film reaches a wider Netflix audience in August.
