Los Angeles ? The nuclear terrorism thriller “The Sum of All Fears” continued to add up with moviegoers, taking in $18.7 million to remain the No. 1 film for a second weekend.

“Divine Secrets of the Ya-Ya Sisterhood” opened in second place with $16.35 million, according to studio estimates Sunday.

“Bad Company,” another film about a stray nuclear device, proved a bit of a bomb. It debuted in fourth place with just $10.5 million.

Rounding out the top five were the year’s biggest hits. “Star Wars: Episode II Attack of the Clones,” was No. 3 with $13.9 million, lifting its total to $255 million after 25 days.

“Spider-Man” came in fifth with $10 million for a 38-day total of $370.1 million.

The industry rebounded after last weekend, when the overall box office slumped for the first time in nearly four months. The top 12 movies this weekend grossed $101.7 million, up about 8 percent from the same weekend last year.

Still, it was a relatively quiet weekend compared to most of May, when “Spider-Man” and “Attack of the Clones” drove up revenues by 50 percent or more each weekend.

“You get used to expecting record-breaking films every weekend, especially this summer. I think we’re just in a lull,” said Paul Dergarabedian, president of box office tracker Exhibitor Relations. “It’s a little slow now, then some big movie will come along and set the world on fire again.”

Next weekend brings three major releases: the live-action adaptation of “Scooby-Doo,” Matt Damon’s spy adventure “The Bourne Identity” and Nicolas Cage’s war drama “Windtalkers.”

“The Sum of All Fears,” starring Ben Affleck in an adaptation of the Tom Clancy bestseller, has taken in $61.8 million in 10 days and should wind up topping $100 million.

“Ya-Ya Sisterhood” is headlined by Sandra Bullock, Ellen Burstyn, Ashley Judd, Maggie Smith and James Garner in a tale of lifelong friends trying to repair a mother-daughter rift.

The film drew a mostly female crowd but got a positive reaction from male viewers, too, said Dan Fellman, head of distribution for Warner Bros., which released the movie.

“The excellent word of mouth is going to make this movie have some great legs,” Fellman said.
