But before anyone slides into those magical jeans again, Sisterhood has some business to attend to. ''These movies can open to $8 or $9 million or $18 or $19 million, and that's a big swing,'' says Di Novi, who should be comforted by the fact that Disney predicted a $12 million opening for The Princess Diaries, which ended up with $22.9 million. Perhaps the best omen for Sisterhood came in January, when Disney decided to move Herbie: Fully Loaded's release from June 3 to June 22, which will give Sisterhood a three-week running start at the box office. If Lindsay Lohan is leaving skid marks off your release date, those Pants must be pretty damn hot.
