“My Blueberry Nights” — repeat kisses notwithstanding — is a conscious attempt to pick up the pace. For one thing, Mr. Wong shot it in just seven weeks. “We thought of this as a vacation film, spontaneous and contemporary,” he said. “Making a film under the best conditions, it’s like a rock band on tour,” he added, ever the rock-star director: his trademark sunglasses stayed on through the New York night shoots. 　　

For another, Mr. Wong said that the project “happened overnight.” He was in New York last year researching another movie, “The Lady From Shanghai,” a period drama (no relation to the Orson Welles film noir) that would star Nicole Kidman and shoot in Russia, Shanghai and New York. When that was postponed, he decided to make a smaller, off-the-cuff film, which he conceived as a vehicle for Ms. Jones, the Grammy-winning singer-songwriter, who had never acted before. 　　

“She’s a natural,” he said, adding that he had instructed her not to take acting lessons. 　　

As he sees it, “My Blueberry Nights” is in a sense about Ms. Jones’s face as it reacts to different environments. “In Memphis there’s something very classic about her presence,” he said. “In New York it’s very contemporary.”

Ms. Jones seemed less confident than her director. “I have no idea what he saw in me or where he saw it,” she said on a coffee break one night. “When I got the call, I thought he wanted some music for his movies. It’s weird because I feel like I’ve looked uncomfortable in every music video I’ve been in.” 　　

William Chang, who has been Mr. Wong’s editor, production designer and costume designer from the start, is with him on “My Blueberry Nights,” but for the first time in 15 years Christopher Doyle, the iconoclastic Australian cinematographer, is not. Together Mr. Wong and Mr. Doyle invented a much copied visual shorthand for romantic alienation, a mix of neon-smudged kinesis and slow-motion contemplation. But their relationship has been strained of late, with Mr. Doyle’s Hollywood workload and Mr. Wong’s erratic schedules becoming incompatible. In Mr. Doyle’s place is Mr. Khondji, the French cinematographer best known for the dank atmospherics of David Fincher’s “Seven.” 　

Just as striking as Mr. Doyle’s absence from the project is the presence of Hollywood actors. Over the years Mr. Wong has built up a repertory of Hong Kong luminaries who learned to thrive under his impulsive demands. “My Blueberry Nights” subjects its starry ensemble to an open-ended process that would be inconceivable on a studio movie. (The film was acquired for American distribution by the Weinstein Company earlier this month.) 　　

Mr. Wong was also working for the first time with a screenwriting partner, the crime novelist Lawrence Block, who had written some scenes based on an outline. While shooting, Mr. Wong constantly revised and added new scenes, often at the last minute.

He said he was surprised to find that the actors were not only ready for the challenge — his reputation preceded him — but even excited.
