Mariska Hargitay is reclaiming her mother's story — and her own. HBO released the official trailer for Hargitay's directorial film debut My Mom Jayne, which will premiere on HBO and Max on June 27.

In the trailer, Hargitay says that her mother's "career made me want to do it differently, but I want to understand her now." When Hargitay was just three years old, she, along with her two older brothers, survived the car wreck that killed her mother, Jayne Mansfield, then just 34, in 1967.

"I don't have any memories of her," Hargitay says in the trailer. "And then my dad died in 2006. I've never talked to my siblings about their experiences," she says of her sister, Jayne Marie Mansfield, brothers Mickey Hargitay Jr. and Zoltan Hargitay, and youngest brother, Tony Cimber, all of whom are featured in the documentary.

Hargitay also discusses what she calls her mother's "persona" with her siblings as they examine Mansfield's "pin-up" public image. The mother they knew widely differed from the bombshell presented to Hollywood.

Later in the clip, speaking to her youngest brother Tony, Hargitay says that she's "heard things that are really ugly." "I don't know that I want to know those ugly things," says Tony in response. Mansfield was married to Tony's father, Matt Cimber, for roughly a year, during which time they welcomed Tony.

Hargitay also addresses the keeping of family secrets that she's done for years, and how she's gained a newfound understanding that the secrecy doesn't honor anyone.
