Bruno topped the box office this past weekend, ending the Transformers two-week reign while pushing the giant robots all the way down to third place. America was not feeling the love for Beth Cooper which debuted in seventh. Here's the top five:

1. Bruno: $30.6 million
2. Ice Age: Dawn of the Dinosaurs: $27.6 million
3. Transformers: Revenge of the Fallen: $24.2 million
4. Public Enemies: $13.7 million
5. The Proposal: $10.6 million


Just one new release this week and it's rolling out on Wednesday.

Harry Potter and the Half-Blood Prince
What's It All About: The adaptation of the sixth and penultimate novel in J.K. Rowling's Harry Potter series. The threat of Voldemort's return and raging teenage hormones make for an interesting year at Hogwarts.
Why It Might Do Well:
Apparently the first trick they teach the kids at Hogwarts is how to conjure up currency as the series has proven to be a license to print money. A 95% rating at Rottentomatoes.com suggests the trend will probably continue.
Why It Might Not Do Well:
Rowling's books got quite a bit longer as the series progressed. The film version of Harry Potter and the Order of the Phoenix felt like a Cliff's Notes version of the novel, hitting the highlights but not quite jelling in my humble opinion. Might the Half-Blood Prince do the same?
Number of Theaters:
4,250
Prediction:
$96 million
