Los Angeles ? People rushed to theaters to see the buddy cop comedy “Rush Hour 3,” making the last of this summer’s big budget Hollywood films the top movie at the weekend box office.

The film took in $50.2 million, according to studio estimates, enough to push last week’s top film, “The Bourne Ultimatum,” into second place with $33.7 million.

“Rush Hour 3” did not do as well as its predecessor, “Rush Hour 2,” which took in $67.4 million when it was released in 2001. But it was the sixth “threequel” of the summer to open as a weekend’s top film, and it ranks as the fourth best August opening on record.

“The Bourne Ultimatum” crossed the $100 million mark in its second week in theaters. And with “The Simpsons Movie” coming in third with $11.1 million, for a three-week total of $152 million, Hollywood might be looking at its first $4 billion summer.

“We’ve been riding a wave of momentum that started with ‘Transformers’ in July,” said Paul Dergarabedian, president of box-office tracker Media By Numbers. “We already stand at $3.6 billion at the box office. The $4 billion summer, once thought an impossibility, is definitely within reach.”

Estimated ticket sales for Friday through Sunday at U.S. and Canadian theaters, according to Media By Numbers LLC. Final figures will be released Monday.
