Mariska Hargitay: the documentary about her mother that turned into a film about herself

The choice Mariska Hargitay had to make, once she decided to direct My Mom Jayne, was not whether to be honest about Jayne Mansfield — she had studied her mother’s life for decades. The harder question was whether the film could be honest about her. An actress who had spent twenty-five years playing Olivia Benson, the survivor-advocate who could absorb anyone’s worst night and keep working, might have expected directing to feel like an extension of performance. What happened instead, by Hargitay’s own account, was that something “got unleashed, or broken open, or freed.” Making a documentary about her mother turned out to require telling the truth about herself.

She was born on January 23, 1964, in Santa Monica, California, the youngest of three children of actress Jayne Mansfield and her second husband, Mickey Hargitay. On June 29, 1967, Mansfield died in a car accident in Louisiana. Mariska was three, sitting in the backseat; she and her brothers survived. The version of her mother she would grow up with was the one the world had constructed — the sex symbol, the comparison to Marilyn Monroe, the woman reduced to a persona. Growing up with Mickey Hargitay, who died in September 2006, Hargitay resisted that image. “I didn’t like the sex symbol aspect of her personality,” she has said. “She was so much more.” That tension — between the public construction of a woman and who the woman actually was — would organize thirty years of Hargitay’s professional life.

She trained at UCLA’s School of Theater, Film and Television, then at the Groundlings Theatre in Los Angeles, and was crowned Miss Beverly Hills USA in 1982 before her first screen credit: the 1985 cult horror film Ghoulies. Guest spots and recurring roles accumulated through the late 1980s and ’90s — fifteen episodes of Falcon Crest, a recurring part in ER — but the defining role hadn’t arrived.

It arrived in 1999, when Hargitay was cast as Detective Olivia Benson in Law & Order: Special Victims Unit, Dick Wolf’s procedural built around sex crimes investigations in New York City. The role that was supposed to be an ensemble part became something else. Benson’s biography — raised by a mother who had been raped, conflicted about whether her own origin made her more or less capable of doing the work — resonated in ways that crime procedurals rarely sustain past a season. Law & Order: SVU is now in its twenty-eighth season, and Hargitay has appeared in every episode, through maternity leave and stunt injuries and Benson’s gradual transformation from detective to lieutenant to captain. She holds a record that no American primetime performer has matched: the longest continuous run as a single character in the history of the form.

That durability was not only a function of the show’s staying power. From the beginning, Hargitay understood Benson as connected to something she could not entirely perform. “It’s no accident that I play somebody who fights for abused women,” she has said. In 2004, she founded the Joyful Heart Foundation, initially to support survivors of sexual assault and later extending its mission to domestic violence, child abuse, and human trafficking. She has campaigned for the Violence Against Women Act, run a major advocacy effort to eliminate the backlog of untested rape kits in the American justice system, and in 2024, disclosed publicly that she is herself a rape survivor.

The question the Benson years could never quite resolve was whether the character had become a cage. The show’s extraordinary run — and its genuine social utility, through the reform campaigns and survivor support infrastructure Hargitay has built alongside it — created a category problem for her as an artist. She was not only an actress; through sustained effort she had become a figure inseparable from the causes Benson represents. When she has discussed the limits of that identity, Hargitay has been precise: “The comedy thing was painful to me, because I felt like I was only exercising one part of myself.” The documentary changed that. Not because My Mom Jayne is anything other than serious, but because directing required her to be a maker rather than an interpreter — to make choices rather than receive them. Something, she said, “got unleashed.”

My Mom Jayne premiered at the Cannes Film Festival on May 17, 2025, and arrived on HBO and Max on June 27. The documentary reveals, among other things, the identity of Hargitay’s biological father: Nelson Sardelli, an Italian-American entertainer who had a relationship with Jayne Mansfield during a brief separation from Mickey Hargitay in 1963 and 1964. Hargitay had known this privately since her twenties, but had not disclosed it publicly. “I grew up where I was supposed to,” she said. “I’m Mickey Hargitay’s daughter — that is not a lie.” The film earned a perfect score on Rotten Tomatoes, the Producers Guild Award for Outstanding Documentary Motion Picture, and two Creative Arts Emmy Awards in September 2026 — for Outstanding Documentary or Nonfiction Special and Outstanding Directing for a Documentary/Nonfiction Program. It was her first Emmy in twenty years, and her first as a filmmaker.

The same year, Hargitay made her Broadway debut in Duncan Macmillan and Jonny Donahoe’s solo play Every Brilliant Thing, performing at the Hudson Theatre from May 26 to July 5, 2026. The play, in which a narrator assembles a lifelong list of reasons to stay alive, works in the same territory she has mapped for a quarter century — survival, the weight of what people carry — but requires a different instrument: presence without character, a performer rather than a detective.

She has been married since 2004 to actor Peter Hermann, whom she met on the set of Law & Order: SVU. They have three children: a biological son born in 2006 and two children adopted in 2011. Hargitay speaks five languages: English, French, Hungarian, Spanish, and Italian.

She is currently filming Law & Order: SVU Season 28, which will premiere in fall 2026 on NBC. On September 14, 2026, she hosted the 78th Primetime Emmy Awards — the first woman to host the ceremony in fifteen years — a culmination of a year that began at Cannes and has not finished opening doors she had not known were there. “What if I wasn’t afraid?” she said, describing the decisions she made in the eighteen months leading up to it. “What do I want to do?” Season 28 is the answer for now. It will not be the last one.
