Harry Potter and the Half-Blood Prince is on fire. The movie scored the highest-grossing five-day start for any Harry Potter movie to date, coming in just shy of $160 million earned (about half of which came over the weekend itself). Someone also managed to find a box office record that it broke as well — the biggest opening ever overseas ($237 million). Ice Age: Dawn of the Dinosaurs and Transformers: Revenge of the Fallen stayed near the top of the charts, while Bruno fell to #4 with a massive 73% drop-off. No surprise there. The Hangover once again proved to be the summer comedy with staying power, as it continued to hang in the top 5.
