G.I. Joe and Julie and Julia hit their respective demographics head on while the thriller A Perfect Getaway landed way back there in seventh place. Here's the top five:

1. G.I. Joe: The Rise of Cobra: $54.7 million
2. Julie & Julia: $20 million
3. G-Force: $9.8 million
4. Harry Potter and the Half-Blood Prince: $8.9 million
5. Funny People: $7.9 million

Can't remember the last time we had five new releases in one week, but here we are:

What's It All About: High school friends join forces to form a band to compete in a competition that may win them a recording contract.
Why It Might Do Well:
There are only six reviews in at the moment but Rottentomatoes.com gives it 67% fresh.
Why It Might Not Do Well:
Seems kind of like a cross between High School Musical and The Rocker with no star power to speak of.
Number of Theaters: 2,000
$7 million

District 9
What's It All About: Thirty years ago a space ship carrying the last survivors of an insect-like alien race landed in South Africa. The alien refugees have been housed in District 9 and the governments of the world are fighting for control of the aliens' technology.
Why It Might Do Well:
Peter Jackson is serving as producer, the trailer looks pretty cool, and although only fifteen reviews have been tallied so far Rottentomatoes.com is giving a whopping 100%.
Why It Might Not Do Well: I suppose it's possible that someone might find the resemblance to Alien Nation off-putting.
Number of Theaters:
$36 million
