Mariska Hargitay’s feature film directorial debut is deeply personal.

In her new documentary “My Mom Jane,” the “Law & Order SVU” star searches for answers about her late mother, Jayne Mansfield, who died in a tragic car accident at the age of 34.

“There’s so much pain left in the unsaid,” Hargitay told the New York Times last week, adding, “I just wanted to say it. I’m not scared.”

While the film premiered last month at the Cannes Film Festival, it’s finally available on streaming services as of today. Read on for everything you need to know to watch it at home.

“My Mom Jayne” airs exclusively on HBO at 8 p.m. ET/PT on June 27, 2025.

The two-hour film hits HBO’s streaming service, Max, at the same time it airs. If you don’t have a subscription already, you can sign up through Prime Video starting at $9.99/month.

Almost six decades after her mom’s tragic passing, Hargitay wove interviews with family members, home movies and archival photos into an intimate portrait of Mansfield — a Hollywood legend and one of the most-photographed stars of the 1950s.

“Her career made me want to do it differently, but I want to understand her now,” Hargitay says in the film’s trailer.

The project also resulted in the public revelation that Mickey Hargitay, who passed away in 2006, is not her biological father — a family secret she’d been holding for more than three decades.
