2. Pineapple Express $22,400,000
3. The Mummy: Tomb of the Dragon Emperor $16,113,000

10. Wall-E BV $3,045,000
11. Space Chimps $1,650,000
12. Hellboy II: The Golden Army $1,254,000

The amazing story for the weekend is The Dark Knight taking out top spot for an incredible fourth weekend in a row. This is a rare occurrence in this day and age of Hollywood blockbusters. It's current box office total stands at a phenomenal 441.5 million.

The new stoner movie, THE PINEAPPLE EXPRESS, took out top spot on Friday but settled for second. This is a great result for this film as its budget is only 27 million.

The other new opener THE SISTERHOOD OF THE TRAVELLING PANTS 2 will have to work a little to recoup its budget of 27 million with a softer opening of 10.7 million.

THE MUMMY: TOMB OF THE DRAGON EMPEROR fell back to Earth this weekend, losing 60% of its audience from the previous weekend. The current total for the film stands at 70.6 million and combined with overseas grosses, the film is likely to make its money back but not impressively enough to warrant another entry in the franchise.

Hancock, Wall-E and Mamma Mia! are all hanging in the top 10, consistently bringing in decent box office takes each weekend since their openings.

The total box office for 8-10 August 2008 at the North American Box Office came to 109.5 million.
