The summer blockbuster season has finally come to an end, with the box office slowing down during the hot North American summer.

The new Vin Diesel film, BABYLON A.D., opened in top spot on Friday with 3.1 million. With a budget of 70 million, this is hardly a great start but we'll have to wait and see what happens.

TROPIC THUNDER nestles in to second spot with another 3 million. It's total is now up to 75 million and is getting close to breaking even at the domestic box office.

THE HOUSE BUNNY plummets to third, taking in another 2.6 million. The Don Cheadle starrer TRAITOR opened in fourth with 2.2 million, but given its more adult subject matter, it may end up with the same amount as BABYLON A.D. by the end of the weekend.

The reigning champ of the 2008 box office, THE DARK KNIGHT, is still going strong, although the air is starting to come out of its tires. Batman pulled in another 2.2 million to bring its impressive total to 495 million.

The other notable story is MAMMA MIA! This leggy musical has been sticking around for a long time, not having very significant drops from weekend to weekend. It took in 1.2 million on Friday and has a great total of 128.2 million against a production budget of 52 million

The North American box office in total took in 19.8 million for the whole of Friday 29th August 2008.
