Let’s face it: Daniel Radcliffe may be cute, but guinea pigs are cuter.

Despite earning $78 million last weekend, Harry Potter and the Half-Blood Prince could not keep up the magic. The sequel fell to second place after earning a still impressive $29.5 million take over the past three days. Overall, the film has raked in $220 million to date and a delayed opening in IMAX theaters this Wednesday - Transformers 2 had been taking up room - should give the film another boost.

So what could possibly scoot the wizards out of first place? Rodents. Disney, which has already seen The Proposal and Up premiere on top this summer, earned another victory with the debut of G-Force. The comedy about a bunch of whiskered CIA operatives roped in $31.6 million over the weekend, just enough for a close win.

Meanwhile, Sony’s The Ugly Truth still managed to find an audience for its R-rated humor. The romantic comedy, starring Katherine Heigl and Gerard Butler, pulled in $27.6 million for a third place finish. It also averaged $9579 per screen - the most for any movie in the Top 10.
