LOS ANGELES: In an unusual matchup, big-budget Hollywood action thriller “Cowboys & Aliens” shared the top box office spot this weekend with kid animation “The Smurfs,” industry estimates showed Sunday.

“Cowboys,” with reported production costs of around dollar 163 million and starring Hollywood A-listers Harrison Ford and Daniel Craig as cowboys warding off an alien invasion in the 19th century Old West, pocketed dollar 36.2 million for its opening weekend, according to industry tracker Exhibitor Relations.

Those figures were on par with ticket receipts from the small blue Smurf creatures first created by a Belgian cartoonist more than 50 years ago, likely riding on a wave of family appeal. Some theaters offered the film in 3D.

In third spot, “Captain America: The First Avenger,” featuring the beloved comic book hero, took in dollar 24.9 million during its second week of showing, ahead of “Harry Potter and the Deathly Hollows - Part 2.”

During its third week in theaters, the eighth and final episode scored dollar 21.9 million, for a total of dollar 318.5 since its smash release in early July.

In the latest of its record-breaking run, Warner Bros. Pictures said “Deathly Hallows” had crossed the dollar 1 billion threshold in worldwide ticket receipts, the first in the series and only the ninth film in cinematic history to do so.

The company said the film had earned about dollar 690 million outside North America, for a total of dollar 1.008 billion, making it the top-grossing film in Warner Bros. Pictures' history.

Other records for the film include one for single-day ticket sales (dollar 92.1 million) and another for midnight premiere sales (dollar 43.5 million).

“What's truly astounding is that these kinds of numbers are being achieved so early in the film's release,” said Warner Bros. Pictures president of domestic distribution Dan Fellman.

Adult romantic comedy “Crazy, Stupid, Love” raked in dollar 19.3 million. A middle-aged father played by Steve Carell learns how to get women as he deals with the adulterous tendencies of his wife (Julianne Moore) for this new release.

Sixth place went to “Friends with Benefits,” a romantic comedy starring Justin Timberlake and Mila Kunis. It sold dollar 9.3 million in tickets during its second weekend in theaters.

Dark comedy “Horrible Bosses” netted dollar 7.1 million, while “Transformers: Dark of the Moon” took dollar 6 million.

Sony's “Zookeeper” got dollar 4.2 million, ahead of 10th place finisher “Cars 2,”with dollar 2.3 million.
