Isabelle Huppert on the Importance of the Venice Film Festival

Actors often have more than one project on the boil. The French actress Isabelle Huppert takes multitasking to the next level.

For the next 11 days (Wednesday through Sept. 7), Huppert is heading up the jury of the Venice Film Festival, watching nearly two dozen movies (together with the other jurors) and handing out awards, including the coveted Golden Lion.

In the days and weeks leading up to the festival, Huppert has been working nonstop.

Earlier this week, for two nights in a row, Huppert performed alone onstage at the Ruhrtriennale festival of the arts in Germany, delivering the 100-minute monologue “Bérénice” (an adaptation by Romeo Castellucci of the 17th-century French tragedy by Jean Racine).

Days before that, she was on a film set in Belgium, playing a fictionalized version of Liliane Bettencourt — the billionaire heiress to the L’Oreal cosmetics fortune — in “La Femme la plus riche du monde” (“The World’s Richest Woman”).

Huppert’s résumé is correspondingly impressive. She has more than 120 films to her name, as well as an Academy Award nomination (best actress in 2017 for “Elle”) and quite a few theater productions. She manages to toggle between film and stage acting, appearing regularly in cinemas and theaters around the world.

Fresh off the set in Belgium, and busy relearning her lines for “Bérénice,” Huppert discussed film festivals, the future of cinema and the American stage director Robert Wilson in a recent phone interview. This interview was conducted in French and has been edited and condensed.
