'Transformers' Fends Off 'Horrible Bosses' At Box Office

'Dark of the Moon' becomes highest-grossing film of 2011.

"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.

"Bosses" outperformed any of the films released by its stars in 2010, but the debut of "Zookeeper" didn't rank highly in the filmography of Kevin James. Originally intended for a summer 2010 release, "Zookeeper" opened with $21 million to land at #3 on the box-office scorecard. Produced by Adam Sandler's Happy Madison (and featuring a monkey voiced by Sandler), the animal-heavy rom-com opened better than "The Dilemma" but didn't come close to "Paul Blart: Mall Cop."

"Cars 2" dropped to #4 with $15.2 million. The animated sequel is the least-attended movie in Pixar's history and has a three-week total of $148.8 million. Cameron Diaz's "Bad Teacher" was #5 with $9 million for a three-week total of $78.7 million, which is almost four times its estimated production budget.

This weekend's new releases include a little movie about a wizard named Harry Potter.
