For Leading Lady, the new biography of Sherry Lansing, the legendary film executive had to do something she never did during her 12 years running Paramount Pictures: relinquish control. Lansing, 72, participated in the biography but she and her husband, filmmaker William Friedkin, granted author Stephen Galloway full autonomy to research her life, talk to dozens of her closest friends (and not-so-close collaborators) and write the book as he saw fit. Having read the final product after four years of interviews, Lansing invited THR to her Century City office (overlooking the Fox lot, which she famously ran as the first female studio boss in 1980) to talk about being the subject of a biography, reliving her mother's death from cancer, her hopes for Paramount today and her new life as a philanthropist (Stand Up to Cancer, which she co-founded, has raised about $500 million to fight the disease). Is Lansing scared what people will think of the book? "Terrified," she says.
