The Japanese writer Haruki Murakami, according to the literature accompanying the new film “Blind Willow, Sleeping Woman,” is a rock star — or at least that’s what the author’s agents told Pierre Földes when he broached the subject of making a movie based on Mr. Murakami’s short stories. Also, unsubstantiated reports labeled the author mercurial and dismissive and said he “detested” animated pictures — which was, alas, Mr. Földes’s intended medium for the project.
