A collection of programmes from the BBC series 'Walking with Dinosaurs'. The BBC used state of the art computer graphics, combined with established historical fact to trace the evolution and 160 million year history of the dinosaurs. The techniques employed by Stephen Speilberg in his 'Jurassic Park' movies are used here to bring the long-extinct behemoths and the world in which they existed to life. The set comprises: 'Giant Claw', 'Land of the Giant Dinosaurs', 'Walking With Dinosaurs' and 'Ballad of Big Al'.
