Dinotopia (TV miniseries)

A pair of teenage half-brothers, Karl and David Scott, are on a flight with their father on his private plane when Karl takes over the controls, allowing his father to fall asleep. After flying into a storm, Frank retakes control before it crashes into the ocean. Frank had trouble escaping the crashed plane, but the brothers wash up on the shore of a large uncharted island. Looking for help, Karl and David find a man named Cyrus Crabb who leads them to Waterfall City, the capital of Dinotopia, a hidden civilization where human beings and dinosaurs peacefully coexist. In fact, some of the dinosaurs, notably a neurotic Troodon named Zippo, possess human intelligence and speak perfect English. Among the many rules in Dinotopia is the edict that, once an outsider arrived, he or she was never allowed to leave. As Karl and David prepare to take their places in their new surroundings, both boys develop a strong bond with young Marion, who is on the verge of becoming a "matriarch" of the Dinotopian society. Unfortunately, the incursion of vicious carnivores, not to mention an unanticipated human villain, threaten to destroy Dinotopia and everyone living on the island.
