Overview

  • My Mom Jayne premiered at Carnegie Hall on June 13 as part of the Tribeca Festival following its world debut at Cannes, marking Hargitay’s feature directing debut.
  • The documentary combines archival footage, family letters and interviews with her siblings to chart Jayne Mansfield’s Hollywood career and the 1967 car crash that nearly left Mariska trapped under the passenger seat.
  • Hargitay publicly confirms for the first time that Italian singer Nelson Sardelli, not Mickey Hargitay, is her biological father, a secret she learned in her 20s.
  • She describes the making of the film as a cathartic, rewarding journey of self-discovery and reclamation of her mother’s story.
  • Intimate moments such as the surprise reveal of Mansfield’s white grand piano by her husband Peter Hermann punctuate the film ahead of its June 27 HBO and Max premiere.
