Los Angeles ? The animated fish story “Shark Tale” swamped the competition, opening as the top weekend movie with $49.1 million and potentially breaking the record for best October debut.

John Travolta and Joaquin Phoenix’s firefighting adventure “Ladder 49” premiered in second place with $22.8 million, according to studio estimates Sunday.

The new flicks bumped the previous weekend’s top movie, “The Forgotten,” to third place with $12 million, raising its 10-day total to $38.3 million.

“Woman, Thou Art Loosed,” starring Kimberly Elise as a woman traumatized by childhood sexual abuse who lands on Death Row, opened at No. 6 with $2.5 million. Adapted from the book by Texas church leader T.D. Jakes, the movie opened in narrower release of 408 theaters, about a tenth of the number for “Shark Tale.”

“I (Heart) Huckabees,” an ensemble comedy from David O. Russell (“Three Kings”), had a spectacular debut in limited release, taking in $300,062 in four New York City and Los Angeles theaters. The movie averaged a whopping $75,016, compared with $12,226 in 4,016 cinemas for “Shark Tale.”

“Huckabees,” whose cast includes Dustin Hoffman, Lily Tomlin, Jason Schwartzman, Naomi Watts, Jude Law and Mark Wahlberg, gradually expands to nationwide release through October.

“Going Upriver: The Long War of John Kerry,” a documentary from George Butler (“Pumping Iron”), opened weakly with $303,000 in 160 theaters for a $1,894 average. The movie chronicles the Democratic presidential candidate’s Vietnam service and his subsequent stand against the war.

“Shark Tale” and “Ladder 49” lifted Hollywood out of its box-office doldrums. The top 12 movies took in $104.4 million, up 30 percent from the same weekend last year, the first increase after four straight weekends of declining revenue.

“The box-office has been flatlining for the last month. September was absolutely abysmal,” said Paul Dergarabedian, president of box-office tracker Exhibitor Relations. “So ‘Shark Tale,’ and to a lesser extent, ‘Ladder 49,’ really jump-started the marketplace.”

If numbers hold when final figures are released today, “Shark Tale” would set a record among October debuts, topping the $48.1 million opening of last year’s “Scary Movie 3.”
