Santa Claus (search) could not conquer "The Incredibles."

The cartoon hit retained the top slot at the box office for a second weekend, taking in $51 million and easily fending off animated newcomer "The Polar Express," a Christmas tale that debuted at No. 2 with $23.5 million.

The heist flick "After the Sunset," with Pierce Brosnan (search), Salma Hayek (search) and Woody Harrelson, opened in third place with $11.5 million, according to studio estimates Sunday.

Getting a jump on its full premiere next weekend, Renee Zellweger's sequel "Bridget Jones: The Edge of Reason" began in narrower release and came in at No. 4 with $8.9 million. The film debuted in 530 theaters, compared to 3,650 for "The Polar Express."

The horror tale "Seed of Chucky," a follow-up to the "Child's Play" movies about a bloodthirsty doll, debuted in fifth with $8.8 million.

Hollywood broke out of a box-office slump that has lingered most of the fall. The top 12 movies took in $136 million, up 11 percent from the same weekend last year.

Pixar Animation's "The Incredibles," about a family of superheroes pressed into action after years of civilian life, lifted its 10-day total to $144.1 million. That matched the 10-day total of Pixar's "Finding Nemo," which went on to gross $340 million last year.

The film's revenues held up strongly, down just 28 percent from its opening-weekend gross, indicating it should have a strong shelf life through the holidays.

"I've always learned not to make long-range forecasts, but this is obviously going to go on to be a huge success," said Chuck Viane, head of distribution for Disney, which released "The Incredibles." "If it happens to mirror 'Nemo,' that would be the best of all worlds for us."

"The Polar Express," based on the children's book about a boy's train trip to the North Pole, has grossed $30.8 million since opening Wednesday. Directed by Robert Zemeckis, the movie features Tom Hanks in multiple roles, including Santa, his images captured by infrared sensors through a digital process called performance capture.

With a reportedly $170 million budget, "The Polar Express" needs strong holdover business through the holidays to avoid becoming a box-office train wreck. The movie received wildly mixed reviews, some critics calling it a potential Christmas classic and others saying its hyper-realistic human figures resembled dead-eyed zombies.

Distributor Warner Bros. is confident "The Polar Express" will follow the usual pattern of Christmas family flicks, holding up well through Thanksgiving weekend and beyond, said Dan Fellman, the studio's head of distribution.

"Our movie was made for the holiday season," Fellman said. "Momentum for us is on the climb, which is exactly what our strategy was, to get ourselves some money in the bank and have some great word of mouth before we really hit the holidays."

"The Polar Express" also should become a perennial revenue producer on video and television in future holiday seasons, Fellman said.

Two limited-release films debuted strongly in New York City and Los Angeles. Johnny Depp's "Finding Neverland," in which he plays "Peter Pan" creator J.M. Barrie, grossed $240,016 in eight theaters. Liam Neeson's "Kinsey," a film biography of sexuality researcher Alfred Kinsey, premiered with $175,026 in five theaters.
