Fox's Live Free or Die Hard, starring Bruce Willis, took in $9.1 million when it premiered on Wednesday -- good, but hardly overwhelming -- leading box-office analysts to predict that the stand-out movie this weekend will be the new Disney cartoon starring a rodent whose name is Remy, not Mickey. There is wide disagreement among them about how much Ratatouille is likely to earn, with many expecting it to be the lowest-grossing movie for a Pixar movie ever, falling below last year's Cars, which debuted with $60.1 million.
