Ice Age: Dawn of the Dinosaurs

After Sid (John Alberto Leguizamo) pilfers some dinosaur eggs, Manny (Ray Romano), Diego (Denis Leary) and the rest of their prehistoric pals enter a mysterious, underground world to rescue the hapless sloth. During the course of their mission, the gang encounters many creatures great and small, including hungry carnivores and a relentless, dinosaur-hunting weasel named Buck.
