‘Forbidden Kingdom’ reigns over box office

You’re all right, Sarah Marshall, but you’re no Jackie Chan or Jet Li.

The martial arts adventure “The Forbidden Kingdom,” a Lionsgate Films and Weinstein Co. release that paired Li and Chan for the first time, topped the weekend box office with an estimated $20.9 million in ticket sales.

Universal Pictures’ “Forgetting Sarah Marshall,” the latest risque romantic comedy from producer Judd Apatow, opened a solid No. 2 with $17.3 million. The studio had marketed the breakup comedy through a novel campaign featuring billboards with slogans such as “I’m so over you, Sarah Marshall.”

The Al Pacino thriller “88 Minutes” from Sony Pictures bombed with $6.8 million in its launch, while the weekend’s other wide release, the controversial Ben Stein documentary “Expelled: No Intelligence Allowed” from Rocky Mountain Pictures, cracked the top 10 with $3.2 million.

Overall box-office revenue rose from the same weekend in 2007 for the first time after four “down” weekends, according to data tracker Media by Numbers.
