The Twilight actor is at Cannes to show Come Swim, her film about heartbreak starring a man who can’t quench his thirst

In a suite at the Hotel Majestic Barrière in Cannes, every surface heaves with haute couture. Chanel dresses spun from gossamer threads are draped along the walls and chunky, diamond-studded bracelets are scattered across the dresser. Only the suite’s occupant doesn’t seem to have received the memo. Kristen Stewart, dressed in a vest and black cargo pants, her hair in a blond crop, looks almost defiantly out of place.

But Stewart is not quite the incongruous presence she might seem at the festival. In 2014, she became the first female American actor in 30 years to win a Cesar, for best supporting actress in Olivier Assayas’s Clouds of Sils Maria. More recently, there was her bewitchingly odd performance in Personal Shopper, Assayas’s strange, sad, ruminative ghost story.
