A French literary classic, “Bonjour Tristesse” (translates as “Hello Sadness”) was a publishing sensation in 1954 with its wise beyond her years 18-year-old author Francoise Sagan.

This week, yet another film version arrives with its twisted study of a teenager, her widower father (Denmark’s Claes Bang), his mistress and a family friend gathered for a steamy summer in their spectacular Cote d’Azur digs.

For Chloë Sevigny, 50, “Bonjour” continues a recent high-profile career wave, following two Ryan Murphy series: “Feud: Capote vs. The Swans” where she was socialite and gardener-entrepreneur C.Z. Guest and “Monsters: The Lyle and Erik Menendez Story” as murdered housewife and mother Kitty Menendez.

“I’m just happy to still be working and that they’re interested in me. I’m getting these great opportunities throughout television and the indie world,” Sevigny, just 19 when she made her film debut, said in a Zoom interview.

“Still,” she added with a smile, “not so much from the studio system. But I love working.”

As for “Bonjour,” her Anne, a fashion designer and longtime family friend, is a disruptive force between dad and his only child who might be growing up a little too fast, too soon.

Sevigny signed on in support of writer-director Durga Chew-Bose’s film debut — and because she liked Anne.

“She has a real elegance to her, a real determination of practicality, but also a vulnerability. There were a lot of dualities, which I found interesting.

“And I really believe in Durga as a filmmaker and these really up and coming actors, and happy to be able to support them in their careers. I like to do service to other men and women in the industry. If I can.

“I also,” she added, “like the examination of a father-daughter story that was very close to my father. I hope you see that right off on the screen. That was interesting to me, as far as movies are concerned.”

The Menendez family could not be farther from this “Bonjour” family. Both Kitty and her husband José (Javier Bardem) are presented, along with their sons, in intentionally different views in each episode, ranging from sadists to victims.

“That was challenging,’ she acknowledged. “Because as an actor, you want to play the ‘truth’ of the character, and this ‘truth’ was shifting with each episode and each person’s interpretation of the events. So that was a new challenge for me as an actor.

“It was so dark. It was so hard to go to all those dark places. I’ve never been asked to do that. But that’s, of course, so exciting as an actor. You want those kinds of opportunities you haven’t done before.”

One opportunity she hopes to realize: Moving to Provincetown. “Hopefully that will become real in the next five years.”
