When the BBC turns Simon Doonan's memoir, Nasty: My Family and Other Glamorous Varmints, into a sitcom, he hopes everybody's-first-pick, Oscar-winner Linda Hunt, will play him. "Linda would be great," says the creative director of Barneys, "and she's about my size. I'm just 5-foot-41/2 on my passport." The series, produced by Jon Plowman of The Office and Absolutely Fabulous fame, will be "deranged, wacky and brilliant," says Doonan, and "they might even have me play my own grandmother." (Page Six)
