Not since Julia left Kiefer at the altar have the media’s pryings been greeted with such resounding no-comments. Stanley Kubrick, director-writer-producer of such films as A Clockwork Orange and 2001: A Space Odyssey, is up to something for the first time since making 1987’s Full Metal Jacket, and everyone who’s anyone knows absolutely nothing about it. There are only the rumors: that Kubrick is making a film based on Louis Begley’s 1991 book, Wartime Lies (a first novel about a Polish Jewish boy during World War II), that he will begin shooting in Eastern Europe later this year, that Joseph Mazzello (the little boy in Jurassic Park) will star, and that Julia herself has expressed interest in a role. The people at Warner Bros., which has dibs on distributing the film, will say only that ”there should be some information soon.” Soon being? ”When it’s ready.” And when we cut to the chase and called Kubrick’s London office, assistant Leon politely inquired to what criminal depths we had sunk to obtain the unlisted phone number. Kubrick, needless to say, did not return the call. Well, our lips are sealed.
