Nicole Kidman frolics around in some fields, giggles a lot and just generally looks happy and healthy in her first ad campaign for Swisse Wellness, Australia's No. 1 multivitamin brand. And this isn't just some act. "During the shoot, which took place at the historic Terrara House Estate on the Australian New South Wales south coast, Ms. Kidman surprised the crew by diving into the Pacific Ocean for a spontaneous early morning swim at Seven Mile Beach," the brand tells us. "She drove a pickup truck around the rural estate and enjoyed fresh fruit and vegetables from the garden." See, truth in advertising! The spot, the first of four, was done by Melbourne-based ad agency Noisy Beast, which is said to be planning to open an office in Chicago this year to handle U.S. marketing for the Swisse brand. The shoot was styled by a fellow Australian Oscar winner of Kidman's, costume designer Lizzy Gardiner, and directed by U.S. photographer and filmmaker John Urbano. "I joined Swisse because I wanted to help bring awareness to the importance of living a healthy lifestyle in a busy, often stressful world," said Kidman, who signed up as the brand's global ambassador last year. "I love feeling healthy and fit."
