UPDATE 1-'Horton' triumphs at North American box office

(In paragraph 5, adds international sales for "Horton Hears A Who!")

LOS ANGELES, March 23 (Reuters) - Horton the elephant retained the heavyweight crown at the North American box office on Sunday, but the Easter holiday failed to prevent overall sales from resuming their downtrend.

"Dr. Seuss' Horton Hears a Who!", a computer-animated fable starring the voices of Jim Carrey and Steve Carell, sold about $25.1 million worth of tickets during the three days beginning Friday, said distributor 20th Century Fox.

After 10 days, the film has earned $86.5 million in North America, matching its production budget. It becomes the first release of 2008 to lead the field for two weekends. Carrey voices the title character, a rubbery elephant who stumbles upon a speck that happens to be a tiny planet, home to a city called Who-ville. Carell voices the excitable mayor.

"People like the film and they can take the whole family," said Bert Livingston, senior VP of distribution at the News Corp (NWSa.N: Quote, Profile, Research)-owned studio.

"Horton" also earned $25.2 million from 49 international markets, including $6.1 million from a No. 1 bow in Britain, and $2.5 million from its second-place start in Australia. Its foreign total rose to $50 million since its opening.

Four movies opened in the North American top 10, led by prolific writer/director Tyler Perry's latest comedy-drama "Meet the Browns" at No. 2 with $20.0 million, roughly in line with his past efforts such as last October's "Why Did I Get Married?" and 2005's "Diary of a Mad Black Woman."

"Meet the Browns" stars Angela Bassett as a single mother struggling to raise three children in Chicago. Perry's films are released by Lionsgate, a unit of Lions Gate Entertainment Corp (LGF.N: Quote, Profile, Research).
