Disney's animal comedy "Beverly Hills Chihuahua" opened at the top of box office in North America, with its US$29 million of ticket sales marking the studio's best October debut ever, preliminary figures showed yesterday.

The film tells a story about a spoiled Beverly Hills female Chihuahua dog, who accidentally finds herself lost in Mexico and must rely on some new friends, including a street-hardened German Shepherd and an amorous pup, on her incredible journey back home.

Dreamworks/Paramount's thriller "Eagle Eye" had minimum drop-off in its second week of release, and was in second place with US$17.7 million over the weekend, according to Los Angeles-based box office tracking firm Media By Numbers.

"Nick And Norah's Infinite Playlist," a comedy drama from Sony Pictures about two teenagers ends up their first date while going on an all-night quest to find their favorite rock band's secret show, enjoyed the next-best opening after "Chihuahua," was on track to take in US$13 million, good enough to open in third place.

Warner Bros.' middle-age love story "Nights in Rodanthe" was in fourth place, taking in US$7.4 million over the three-day period in its second weekend of release, followed by western "Appaloosa" from the same studio with US$5 million.
