Natalie Portman and Jodie Foster shine at the Paris premiere of Vie Privée

Natalie Portman is not part of the film’s cast.

Her presence at the Paris premiere was mainly due to the fact that she is a close friend of director Rebecca Zlotowski, and came to support her on the red carpet.

Since Belle Épine (2010), she has explored intimate portraits, often of women, with a blend of realism and emotional turmoil.

Anne Berest is a French novelist and screenwriter born in Paris. Having made a name for herself with La Fille de son père (2010), she enjoyed huge success with La Carte postale (Prix Renaudot des lycéens, 2021).

Noam Morgensztern is a Toulouse-born French actor who has been a resident of the Comédie-Française since 2013. In Vie Privée, he plays Pierre Hallan (credited as a patient smoker), a secondary but significant role in the film’s universe.

Daughter of Jean-Pierre Cassel and half-sister of Vincent Cassel, she made a name for herself on the silver screen in the 2000s with landmark roles in Vivante, Ô Jerusalem and, above all, Le Premier Jour du reste de ta vie, before developing a parallel pop-electro musical career under the name HollySiz.
