http://www.nypost.com/entertainment/11463.htm New York Post 2000-09-25 By Megan Turner "Last Picture Show" SHE gives us a fleeting glimpse of a prodigious natural talent, scoops up a Best Actress award at Cannes, and then, like the will-o'-the-wisp she resembles, Bjork is gone. The fey Icelandic singer says her first acting performance - a wrenching, emotionally naked turn as a childlike Czech immigrant in Lars von Trier's musical melodrama "Dancer in the Dark" - will also be her last. She stresses, however, that this is not because of the famously difficult time she had on the Danish set, where she immersed herself so thoroughly in her put-upon character that she "started to become her." Nor is she gun-shy because of the reportedly fraught relationship she had with the equally intense, idiosyncratic von Trier. "I don't think I will [act again]," Bjork says during a visit to New York for the film's premiere. "But I want to make very clear that that's not because of this film. "I will jump off a cliff any day - that's not what I'm scared of - and I'll still be attracted to eccentrics, there's no stopping me there. "Before the film, I was never going to act; I was going to devote my life to music." The 34-year-old single mother, renowned for her eccentricity and free- spirited ways, released her first album at 11, achieved international fame as the lead singer of the Sugarcubes, and has released a string of successful solo albums. She says she made an exception for von Trier's film because "there was such a creative smell in the air" but now all she wants to do is "go back to my musical nest." "Dancer," which won the prestigious Palme d'Or and opened the New York Film Festival Friday, is one of the year's most controversial films. Although the movie itself has bitterly divided the critics - it's been called variously a masterpiece and a sham - Bjork's performance has received nothing but praise. Bjork, who also composed and sings on the soundtrack that accompanies "Dancer's" fantasy sequences, says she decided to talk publicly about the film because she was tired of the rumors. "I didn't do any press for nine months because I don't believe in spelling out secrets about the creative process," she says. "But then I just said, 'I have to defend it,' because this whole drama that's going on about how difficult it was on set, I didn't experience that at all." She says that, contrary to rumor, she and von Trier's relationship, while intense and volatile, was productive. "We were completely linked, and it was very easy for me to surrender to a director and be someone else's tool - I found that very exciting." Problems arose when other crew members began "chopping up" her songs. "I'd say, 'You can't cut 11 bars out of this song because it doesn't make any sense' and they'd say, 'You're just an actress, shut up.' "Every time me and Lars were on our own, everything was fine. We always found a way to compromise; it was more that the people on set started gossiping. "The whole thing was very, very difficult but we solved 5,000 riddles, me and Lars, and I'm very proud of that." Catherine Deneuve, who plays Bjork's best friend in "Dancer," says her co-star "suffered so much" during filming that she's not surprised at her decision to quit while she's ahead. "It's true that there are a lot of films that I can imagine she could do, but I'm sure she won't go back to it," she says. "I think music is her life and she breathes for music and she doesn't want to cry for films." But the veteran French actress believes that, sometimes, one great performance is enough. "I think sometimes you can be the actress of one film," says Deneuve. "And I think she is the actress of that film. No matter what happens in 10 years she will always be remembered for that film. And, even if she does only music for 20 years, people will still ask her about it." Bjork has her own theories on why reaction to the film has been so strong. "I think right now it's the pioneer's movie, and I don't necessarily mean that makes it a good or bad film," she says. "It's like the first people who went to Antarctica - it's quite a brutal thing, it's not a holiday, so you're witnessing a lot of not-very-sweet situations and also a lot of mistakes. "Pioneering has got that experimental nature about it - you do 29 terrible things and then you do one genius thing, but you're willing to go through the 29 things instead of just playing it safe and doing one more film like all the other ones."
