Harry Potter may be hot on the trail of the half-blood prince, but hamsters ruled the box office this weekend, taking over the top spot a mere one week after the boy wizard’s debut. G-Force, a mix of live action and 3D animation, focusing on hamster spies, culled $32.1 million from US audiences to edge out Harry Potter and the Half-Blood Prince, which drew a respectable, but lower than expected, $30 million even.

Not that Harry and company have anything to worry about; their 10-day take has been $221 million in the US alone, and another $405 million in worldwide box office for a total of $627 million overall in only 10 days. Not bad for a move that cost $250 million to make.

The latest Katherine Heigl rom-com, The Ugly Truth, hauled in $27 million, justifying its $38 million modest budget and, perhaps, the use of weight loss diet pills in Hollywood. Horror film Orphan came in fourth with $12.7 million while Ice Age: Dawn of the Dinosaurs underwhelmed its way to $8.2 million in its fourth week to edge out Transformers 2 for the last place in the top five.

Next week should prove interesting as the major releases go for a different audience than the recent slate of action blockbusters and children’s fare; Funny People features a potential dream-pairing of Adam Sandler and Seth Rogan on the screen at the same time, while Aliens In the Attic may suffer from being part of a very large and competitive crowd of children’s films.
