NEW YORK: In “The Clouds of Sils Maria,” Kristen Stewart’s celebrity has been inverted. The paparazzi rush right past her.

She plays the efficient, constantly e-mailing assistant to Juliette Binoche’s famed European actress. Reading tabloid stories about a Hollywood starlet (played by Chloe Grace Moretz), she shrugs: “It’s celebrity news. It’s fun.” When she’s running through possible roles for her boss, the former “Twilight” star describes one film as having werewolves “for some reason.”

“I had to seriously harness the glee that was exploding across my face when I was saying some of those lines,” Stewart said in an interview. “I don’t think that’s what the movie is fully about. It’s not a commentary about the insane nature of the media in the States, especially. But no one knows about that more than me.”

Stewart, 24, doesn’t seem so much like she’s fleeing her teen idol past as she’s already long gone, maybe just glancing back, with a wink. “The Clouds of Sils Maria,” directed by French filmmaker Olivier Assayas (“Carlos,” “Summer Hours“), which opens in theaters April 10, is part of a string of recent and upcoming films Stewart has made in a headlong rush.

“I’m having more fun now than I ever have,” says Stewart. “These movies go by (she snaps her fingers). We made ‘Camp X-Ray’ in 20 days. It’s just better when it’s faster.”

The frenetic pace is in stark contrast to the plodding demands of a five-film franchise like “Twilight.” The movies now are largely independent, and the roles (like in “Sils Maria“) are often supporting or part of an ensemble. She co-starred as Julianne Moore’s daughter in “Still Alice” and played a Guantanamo guard in “Camp X-Ray.” She’s completed a science-fiction romance (“Equals“), a stoner thriller (“American Ultra“) and a New York mugging drama (“Anesthesia“). She’s been filming Kelly Reichardt’s adaptation of Maile Meloy short stories, and she’s to co-star in Woody Allen’s next film.
