Flushed Away is a rip-roaring nautical adventure with a twist: The heroes are a pair of rodents braving the sewers underneath London. Roddy (voiced by Hugh Jackman) is an upper-crust house-mouse who finds himself flushed into the subterranean sewers. Eager to return to his posh home, he enlists the help of a boat-captain rat named Rita (Kate Winslet), who has troubles of her own; namely the kingpin of the underworld, the Toad (Ian McKellen), and his henchmen including the French mercenary Le Frog (Jean Reno). While technically Flushed Away could be considered part of the wave of celebrity-voiced, anthropomorphic-animal movies that hit in 2005-2006 (Madagascar, Over the Hedge, The Wild, etc.), it doesn't inspire the same sense of dรฉjร vu. For one thing, its voice actors are less recognizable than the likes of Bruce Willis and Chris Rock. For another, its look is very distinctive. Like Nick Park's Chicken Run and Wallace and Gromit: The Curse of the Were-Rabbit, it's a joint production of DreamWorks Animation and Aardman Features, and although Park isn't involved, it retains his trademark blocky look of clay animation. But animating the movie by computer rather than by hand allows for some eye-popping tableaux, such as floodwaters rushing through the sewers and an entire town of little animated characters. It's a crazy thrill ride loaded with inside jokes and enough crude humor to earn a PG rating, and the band of singing slugs is also a hoot. --David Horiuchi
