It's no accident Kim Cattrall looks anorexic as the aggrieved wife Judy in "Bonfire of the Vanities." Already slender, she took off 15 pounds so she'd look like "a social X-ray."

"I wanted to get into the skin of Judy," Cattrall revealed. "She is always referred to in the book as the `social X-ray,' and I felt if I looked too healthy, it wouldn't work as well."Her diet: one week on liquid protein only three times daily, another week on one meal a day, plus liquid protein twice daily, then two more weeks on skimpy rations. "Diet drinks were the only sweet thing I could have."
