LOS ANGELES - Jodie Foster's "Flightplan" stayed aloft at the box office, as the airplane thriller took in $15 million to remain the No. 1 movie over a rush of new wide releases.

The science-fiction tale "Serenity," a continuation of writer-director Joss Whedon's cult TV series "Firefly," debuted in second place with $10.1 million, according to studio estimates Sunday.

The overall box office, which had surged since Labor Day, fell back into a slump that has persisted most of the year. The top 12 movies grossed $75.3 million, down 26 percent from the same weekend in 2004, when "Shark Tale" opened with $47.6 million.

The animated fantasy "Tim Burton's Corpse Bride" was No. 3 with $9.8 million, lifting its total to $32.9 million after two weekends in wide release.

After a strong opening in limited release the previous weekend, David Cronenberg's "A History of Violence" expanded and came in fourth with $8.2 million. The film stars Viggo Mortensen as a family man whose tranquil life is shattered by encounters with mobsters.

"Into the Blue," a thriller with Paul Walker and Jessica Alba as divers hunting for treasure in a 150-year-old shipwreck, opened at No. 5 with $7 million.

The sports flick "The Greatest Game Ever Played," which dramatizes the 1913 U.S. Open golf showdown between an unknown amateur (Shia LaBeouf) and a veteran British champ (Stephen Dillane), debuted at No. 9 with $3.75 million.

Roman Polanski's "Oliver Twist," his new take on the Charles Dickens classic featuring Ben Kingsley, flopped in its wide-release debut after a solid premiere in a handful of theaters a weekend earlier.

Polanski's version received mixed reviews, some critics noting the film faithfully adapted Dickens' story but brought little new to the tale of the orphan boy, which has been filmed in many variations for movies and television.
