TROPIC THUNDER took out the weekend in top spot with a respectable 26 million. It's current total sits at 37.3 million after five days. The opening is a little soft, and it may be touch and go if it makes its 92 million budget back at the domestic box office.

The Dark Knight comes in an impressive second with 16.8 million, taking its total box office to 471.4 million. This is a great result for the Caped Crusader, especially with the two new openers this weekend.

STAR WARS: THE CLONE WARS didn't fare so well, opening in third with 15.5 million. Reviews for this weren't so great and only time will tell if it will continue to do well at the box office.

MAMMA MIA! is another great story, continuing to earn respectable figures each weekend. Its current total stands at 116.4 million against a budget of 52 million.

THE PINEAPPLE EXPRESS has become a profitable venture after accumulating another 10 million this weekend. With a small 27 million budget, the film is sitting extremely well at the moment.

THE MUMMY: TOMB OF THE DRAGON EMPEROR is limping closer and closer to 100 million. It took in another 8.6 million this weekend to bring its total to 86.6 million, well short of its 145 million budget.

The total box office for 15-17 August 2008 at the North American Box Office came to 114.6 million.
