The film has now earned $183.04 million in just three weeks at the box office, earning back its $165 million production cost.

Debuting this week at number two is the long awaited rock n' roll comedy Get Him to the Greek, produced by Judd Apatow. The film stars Jonah Hill (Superbad) as a record company assistant who is told by his boss (Sean Combs) that he has three days to get a washed-up, alcoholic rock singer played by Russell Brand (Forgetting Sarah Marshall) from London to Los Angeles for his comeback show.

The film was predicted to earn around $18.2 million this weekend but instead earned roughly $16.1 million. The film was seen on 2,859 screens and earned almost $5,631 on each, which is still a far cry from it's purported $75 million production budget.

Falling back one place from last week to number four is Disney Studios and super-producer Jerry Bruckheimer's adaptation of the classic video game Prince of Persia: The Sands of Time.

Finally, the debut of the family film, Marmaduke, based on the classic comic strip about the beloved canine, couldn't crack the top 5, landing in sixth place. The film features an all-star cast that includes Owen Wilson (Marley & Me), William H. Macy (Fargo), Kiefer Sutherland (24) and Emma Stone (Zombieland).
