The mutants of X2: X-Men United overtook the planet this weekend, grossing $85.9 million in the U.S. and another $69 million overseas. That ranks as the fourth-best debut in history, following Spider-Man and the first two Harry Potter films. Tween superstar Hilary Duff also seems destined for world domination; her Lizzie McGuire Movie opened at No. 2 with a better-than-expected $17 million. Rounding out the top five: Identity (No. 3 with $9.5 million), Anger Management (No. 4 with $8.5 million) and Holes (No. 5 with $6.5 million).
