G-Force

Warner’s Harry Potter and the Half-Blood Prince earned $30m in its second weekend, down a big 61.5% from opening weekend, putting it in second place behind Buena Vista’s animated guinea pigs in G-Force.

G-Force, a 3-D combination of animation and live action, opened with a larger-than-expected estimated $32.2m, an average of $8,697 from 3,697 screens.

G-Force, produced by blockbuster king Jerry Bruckheimer, features a voice cast including Nicolas Cage, Sam Rockwell, Tracy Morgan and Penelope Cruz. The plot is about government trained spies, who happen to be guinea pigs, trying to save the world from an evil CEO.
