NICOLE AND ANNIE: Does Vogue already have a fall cover in the can? Ask Annie Leibovitz and Nicole Kidman — not to mention, of course, editor in chief Anna Wintour. "If you ring up Nicole Kidman and say, 'Annie Leibovitz wants to photograph you for the next cover,' she'll be there that night," Wintour says in the documentary "Annie Leibovitz: Life Through a Lens." And that appears to be exactly what she's done: Wintour just teamed up the duo all the way Down Under for the second time in seven years. Earlier this month, Leibovitz, a pregnant Kidman and approximately 50 production crew members were spotted by a Channel Nine news helicopter in Richmond, just west of Sydney, shooting what turned out to be a feature for Vogue based on Baz Luhrmann's upcoming movie, "Australia." Kidman wore what looked to be an original costume from the film — a period riding habit with full skirts. However, the set was a miniature replica, since filming proper wrapped for the movie four months ago in Sydney, Queensland and the Northern Territory. Sources said, moreover, that it wasn't Leibovitz's only Australian trip over the past 12 months for this particular Vogue shoot. An Outback epic that begins in the mid-Thirties and concludes around the 1942-43 Japanese bombing of Darwin, "Australia" tells the story of English aristocrat Lady Sarah Ashley, played by Kidman, who travels to the Continent to oversee the sale of a cattle property the size of Belgium. The film costars Hugh Jackman, Jack Thompson, Bryan Brown and David Wenham, and is due for a Nov. 18 release — four months after Kidman and her husband, Keith Urban, are due to welcome their first child. Kidman and Leibovitz have worked together many times, and this is the second time they have collaborated in Australia for Vogue: In 2000, the photographer shot the actress at Sydney's Fox Studios on the set of Luhrmann's last feature, "Moulin Rouge." As for which issue's cover Kidman will grace, that has yet to be finalized, sources said, although it's likely to be September, October or November. A Vogue spokesman in New York declined comment on the shoot. — Patty Huntington
