The Cannes Film Festival has a long-standing tradition of showcasing actors-turned-directors; one of the great thrills of this edition’s Un Certain Regard section so far has been the triumphant emergence of Kristen Stewart and Harris Dickinson —both fixtures at the festival in recent years for their performances in films like “Crimes of the Future” and “Triangle of Sadness”—as formidable writer-directors in their own right.

Kristen Stewart reveals a deft directorial hand and a distinct, languid, echoing style in her vividly made, emotionally visceral exploration of the life and times of American novelist Lidia Yuknavitch.

The “Twilight” actor attended France’s Cannes Film Festival where her new film, “ The Chronology of Water ,” held its world premiere last week. She walked the red carpet in an all-white Chanel suit with trouser shorts in which her new tattoo, which reads “MINE” in all capital letters and is positioned on her right thigh, was visible.
