Dustin Hoffman, Whoopi Goldberg, Joe Pantoliano, Jeff Foxworthy, Snoop Dogg, David Spade, Steve Harvey, and Fred Dalton Thompson provide the voices for wisecracking animals in this dumb but harmless live-action comedy for kids. A zebra left behind by a traveling circus is adopted by a thoroughbred horse trainer (Bruce Greenwood) and his preteen daughter (Hayden Panettiere), who takes a shine to the little fella (voice of Frankie Muniz) and trains him to run races. The jokes are pretty weak (as a wiseguy pelican, Pantoliano dispenses every Mafia-movie catchphrase you never want to hear again), and there's a cliched backstory about the girl's mother having died in a fall from a horse. The ever-reliable Greenwood acts up a storm, perhaps unaware that he's in a talking-zebra movie. PG, 94 min.
