'Transformers,' 'Horrible Bosses' Rule The Box Office

TransformersFROM MTV MOVIES: "Transformers: Dark of the Moon" fended off competition from both an R-rated comedy and a family-friendly film as the third entry in the giant robot franchise maintained the #1 position at the box office with an estimated $47 million during its second weekend in theaters.

"Transformers" passed "The Hangover II" to become the highest-grossing film of 2011 thus far with its 12-day domestic haul of $261 million and crossed the half-billion dollar mark worldwide.

"Horrible Bosses" wasn't able to dethrone Michael Bay's CGI heavy explosion-fest but it does bear the distinction of being the only film in the top five with mostly favorable reviews from critics. Jason Bateman, Jason Sudeikis and Charlie Day star in the black comedy, which opened at #2 with $28.1 million.
