G-Force Topples Harry Potter

After just one week at the top of the U.S. box office Harry Potter and the Half Blood Prince has had to make way for G-Force, the first 3-D movie from Jerry Bruckheimer.

It seems that the boy wizard was no match for the elite squad of guinea pigs as they stormed to the top of the box office grossing $32.2 million in it's opening weekend.

Armed with the latest high-tech spy equipment, these highly trained guinea pigs discover that the fate of the world is in their paws.

Tapped for the G-Force are guinea pigs Darwin (voice of Sam Rockwell), the squad leader determined to succeed at all costs; Blaster (voice of Tracy Morgan), an outrageous weapons expert with tons of attitude and a love for all things extreme; and Juarez (voice of Penelope Cruz), a sexy martial arts pro; plus the literal fly-on-the-wall reconnaissance expert, Mooch, and a star-nosed mole, Speckles (voice of Nicolas Cage), the computer and information specialist.

Harry Potter had to settle for second place as it grossed a further $30 million, a 61% drop in comparison to last week's gross. The film has now grossed over $222 million at the global box office.

There was more box office success for Katherine Heigl as her new movie The Ugly Truth, which sees her team up with Gerard Butler, opened at number three.

Orphan opened in fourth. Starring Peter Sarsgaard and Vera Farmiga the couple are left devastated by the death of their unborn child but are terrorised by the child that hey decide to adopt.

Rounding off the top five was animation hit Ice Age: Dawn of the Dinosaurs. This weeks biggest faller was Bruno as it dropped from four to ten.
