Cannes: Kristen Stewart Talks Ghosts, Vampires, Being "Really Sensitive to Energies"

The star, along with director Olivier Assayas, addressed the boos that greeted their new film 'Personal Shopper' at its press screening. "When you come to Cannes, you have to be prepared for everything," the director said.

"Do I believe in ghosts? I don't know, I guess I believe in something," Kristen Stewart said at the press conference for Cannes competition entry Personal Shopper, a sort of ghost story, on Tuesday.

She also told the press pack, "I'm really sensitive to energies, and I truly believe I'm driven by something that I can't really define. It gives me a feeling that we are not so alone."

Given her past role in the Twilight saga, she was also asked if she liked vampires or ghosts better. "Ghosts," she answered quickly, but with a smile declined to elaborate.

Discussing the movie, Stewart said: "It's a ghost story, sure, but the supernatural aspects of it just lead you to very basic questions."

Stewart, who appeared earlier in the festival in Woody Allen’s Cafe Society, was on hand to promote her latest feature, directed by Olivier Assayas, with whom she’s clearly struck up a rapport, having appeared in his 2014 film Clouds of Sils Maria, for which she won a Cesar Award in France.

"We don't talk to each other a whole lot. He never answers my questions," Stewart said about working with Assayas. "There is a communication that is undeniable. There is a flame he lights under my ass that is stronger than I have ever felt."

In their new film — which triggered both boos and applause when it screened for critics on Monday — Stewart plays a young American in Paris who half-believes she’s in contact with her late twin brother.

Stewart and Assayas also discussed the boos that greeted the film's ambiguous ending. "It happens to me once in a while, where people just don't get the ending," said Assayas. "For me, it's the closest I can get to a happy ending. I'm sorry I can t get much further."

He later added: "When you come to Cannes, you have to be prepared for everything." Interjected Stewart: "Everybody did not boo. Let's be clear."

Stewart also discussed people's addiction to cell phones and technology in the digital age, which is part of the movie. "I've been thinking about distractions a lot lately," she said. "I'm absolutely guilty of constant stimuli that [aren't] actually stimulating at all. It definitely says a lot about how we interact with each other and technology. And it's truly terrifying."

Reviews lauded Stewart's performance but were mixed. "Even Kristen Stewart can't save this undernourished mystery," THR's Todd McCarthy wrote in his review.
