Everyone who took part in last week's competition, myself included, failed to foresee The Forbidden Kingdom outdoing Forgetting Sarah Marshall, but the martial arts actioner was the clear winner. Prom Night held on to third place, content in the knowledge that it had already earned back its $20 million budget last week. Here's the rundown:

1. The Forbidden Kingdom: $20.9 million
2. Forgetting Sarah Marshall: $17.3 million
3. Prom Night: $9.1 million
4. 88 Minutes: $6.8 million
5. Nim's Island: $5.7 million

Opening this week, we have:

What's It All About: Tina Fey plays an executive dying to be a mother, and when she finds out she's unable to conceive, she must turn to a flaky but fertile Amy Poehler
Why It Might Do Well: Fey is awesome on 30 Rock, and though I usually get flack for saying this, I thought the Fey/Poehler Weekend Update team on SNL was one of the best in the show's history. And with a supporting cast that includes Sigourney Weaver, Steve Martin and Maura Tierney, I am so there. The 88% fresh rating from Rottentomatoes.com is icing on the cake.
Why It Might Not Do Well: The poster is so darn zany I could just puke.
Number of Theaters: 2,500
$18 million
