Last weekend, the box office exploded with The Dark Knight, which broke the opening weekend record, while Mamma Mia! did what it could in the shadow of bat wings and Space Chimps couldn't reach the top five with its $7.2 million. Matt was almost spot-on with his predictions last week, but I'll try to hold down the fort this week while he's away.

The top five totals:

1. The Dark Knight: $158,411,483 *
2. Mamma Mia!: $27,751,240
3. Hancock: $14,040,178
4. Journey to the Center of the Earth: $12,340,435
5. Hellboy II: The Golden Army: $10,117,815

There's two new wide releases this week -- one for laughs, and one for those who yearn to believe.

Step Brothers
What It's All About: It's the typical new-family scenario with a much older twist. Will Ferrell and John C. Reilly star as spoiled adults who live at home and are less than pleased when their parents meet and get married. Quickly, however, they become best friends who indulge in all the fun things kids do. You know, whispering after lights out, making things... But then their folks have had enough and want to kick them out, spoiling their fun.
Why It Might Do Well: It's Ferrell and Reilly acting like kids, the bunk beds scene is flipping hilarious, and the two actors have a solid following.
Why It Might Not Do Well: The duo's shtick could be getting old, and it still has to face the roaring-forward Dark Knight.
Number of Theaters: 2,800+
Prediction: $23 million
