Beverly Hills Chihuahua finds director Raja Gosnell back on the talking-dog beat (following his live-action Scooby-Doo and Scooby-Doo 2: Monsters Unleased), this time in an ambitious, tongue-in-cheek comedy with a fun cast of onscreen and vocal actors. Piper Perabo plays Rachel, niece of a Beverly Hills eccentric (Jamie Lee Curtis) who spends much of her fortune pampering Chloe (voiced by Drew Barrymore), a spoiled Chihuahua used to pacing through this world with booties on her paws. Chloe gets dog-napped while Rachel takes a vacation in Mexico, and finds protection from a misfit German Shepherd named Delgado (Andy Garcia), who has a painful secret in his past. The two get into and out of a lot of scrapes, trying to stay ahead of a vicious dog (Edward James Olmos) working for the head of an illegal dogfight gambling syndicate. Computer effects turn the film's many four-legged characters into talking critters capable of leaping onto train boxcars and leading the heroine into the Indiana Jones-like ancestral home of the Chihuahua breed. The comedy is crisp and kid-friendly, the story of Chloe rise out of silliness into canine authenticity, plus the film's surprising ambitiousness, are all very winning. --Tom Keogh
