LOS ANGELES | - A lonely little robot made millions of friends during the weekend — and even outgunned Angelina Jolie.

"WALL-E," the Pixar Animation tale of a robot toiling away on a long-abandoned Earth, debuted as the No. 1 movie with $62.5 million in ticket sales, with Jolie’s assassin thriller "Wanted" opening in second place with $51.1 million, according to studio estimates Sunday.

The two movies combined to keep Hollywood on a roll. The top 12 movies took in $179.2 million, up 22 percent from the same weekend last year, when Pixar’s "Ratouille" opened with $47 million.

It was the fifth straight weekend that revenues climbed. Revenues for the summer season that began May 2 are up 6 percent over last year’s record pace, according to box-office tracker Media By Numbers.

The sour economy and high gas prices may be helping to fuel Hollywood’s boom, said Paul Dergarabedian, president of Media By Numbers. Movies tend to thrive when times are tough because they are relatively cheap compared to sports events, concerts and other outings.

The previous weekend’s No. 1 movie, the Warner Bros. comedy "Get Smart," slipped to third place with $20 million, raising its total to $77.3 million.

"WALL-E" maintains the perfect track record of Pixar, the Walt Disney unit that has made nine films, all of them critical and commercial successes, including "Cars," "Monsters, Inc." and the "Toy Story" flicks. "Finding Nemo" and "The Incredibles" put up the biggest opening-weekend numbers among Pixar movies, both pulling in just over $70 million.

Set centuries in the future, "WALL-E" is the story of a rickety, walking trash compactor that humans left running after abandoning the over-polluted planet.

The movie overcame a dialogue challenge — the two main robot characters barely speak, beyond each other’s names — using wildly inventive visuals and sound effects to propel much of the story. mcall
