After putting up with a frustrating delay, eager Muggles rushed to the theaters this weekend in droves. Harry Potter and the Half-Blood Prince kicked off its extended debut with a record-breaking premiere ($22.2 million) at midnight Tuesday. The series’ sixth installment went on to earn $158 million over five days and officially became the biggest international opener of all time ($237 million).

Despite the numbers, there was one film Half-Blood could not beat: The Dark Knight. At this same time last year, the Batman sequel had also racked up $158 million in sales. But that film did it in only three days.

Although no other films premiered in wide release, there were other noteworthy items to report. Last weekend’s champ, Bruno, plummeted a whopping 73% from its first outing with $8.3 million in sales. Meanwhile, The Hangover - which has now grossed $236 million domestically - officially dethroned Beverly Hills Cop to become the most successful R-rated comedy of all time. It now stands behind only The Matrix Reloaded ($281.6 million) and The Passion of the Christ ($370.8 million) on the list of all R-rated films.
