Like Simba, Only He's a Plucky Pachyrhinosaurus "The Lion King" goes prehistoric in "Walking With Dinosaurs," a good-looking extension of the franchise that began as a BBC television series. This family-friendly film combines computer-generated dinosaurs and real settings to tell a story of a herd on the move, struggling to survive and facing a leadership change complicated by budding romance. In other words, not unlike the struggle/change/romance story of "The Lion King." There's even a bird acting as a sort of guide and troubleshooter. John Leguizamo provides the voice of the bird, Alex, and pairs nicely with Justin Long, who is the voice of Patchi, the tale's main character. Patchi is a pachyrhinosaurus who starts out as the runt of the litter but is destined for big things. He has a crush on a female named Juniper (Tiya Sircar), and their slowly blossoming romance is essentially a reworking of the one between Simba and Nala, those animated lions. Patchi also clashes with his brother, Scowler (Skyler Stone), and everything builds to a decisive moment of courage. The movie looks great, the writing is peppered with moments of wit, and there's even an educational component built in as dinosaur facts are displayed on the screen. But be warned: There are genuinely frightening moments, because for a new leader of the pack to be needed, something bad has to happen to the old leader of the pack. "Walking With Dinosaurs" is rated PG (Parental guidance suggested) for vivid scary moments of fire and death.
