Jayne Mansfield's daughter became TV's longest-running primetime drama character
Mariska Hargitay has played Detective Olivia Benson on Law & Order: SVU since 1999, making Benson the longest-running character in American primetime drama. The role reshaped her life: she trained as a rape crisis advocate to prepare, then founded a charity for survivors and produced an Emmy-winning film about untested rape kits.
She was born in Santa Monica on January 23, 1964, to the actress Jayne Mansfield. At three and a half she was asleep in the back seat on June 29, 1967, when a crash in Mississippi killed her mother; Mariska and two brothers escaped with minor injuries, though she still carries a zig-zag scar. Raised afterward by Mickey Hargitay, whom she grew up believing was her father, she learned only in her twenties that her biological father was the Brazilian-born entertainer Nelson Sardelli.
Her early career was a slog shadowed by comparisons with her mother. She was crowned Miss Beverly Hills USA in 1982, studied theatre at UCLA without finishing her degree, and took small parts: the horror film Ghoulies, a recurring role on Falcon Crest, a turn on ER, and a Seinfeld episode in which her character auditions to play Elaine, a role she had once been considered for in real life.
SVU changed everything. At the final 1999 auditions she read alongside Christopher Meloni, and producer Dick Wolf broke the silence afterward by declaring the choice obvious. Her performance has earned an Emmy and a Golden Globe, and her pay rose steadily; Forbes reported she made an estimated $750,000 an episode from acting, producing and syndication, ranking her television's highest-paid actor in 2024. In 2013 her Hollywood Walk of Fame star was placed beside her mother's.
Off screen, Hargitay founded the Joyful Heart Foundation in 2004 to support survivors of sexual assault, domestic violence and abuse. It had raised $20 million by April 2011. Her HBO documentary I Am Evidence exposed the backlog of untested rape kits and won a News and Documentary Emmy. She has spoken publicly as a survivor herself, and in 2025 she made her directing debut with My Mom Jayne, a documentary about the mother she lost.
