Walking with Dinosaurs: 2 discs. £4.58
"Extending the computer animation techniques developed for Jurassic Park (1993) these six 30-minute programmes, narrated by Kenneth Branagh, became the first blockbuster special-effects documentary. Here was natural history with a difference, recreating "the lost world" of the Cretaceous and Mesozoic with modern technology, the remarkable visuals enabling the programme-makers to show what life may have been like during the estimated 160 million years "when dinosaurs ruled the Earth".
Walking with Monsters: 1 disc. £4.97
" From the makers of Walking With Dinosaurs and Walking With Beasts this is an epic and entertaining new exploration of life before dinosaurs, when a succession of fantastical animals and plants ruled the planet. With the aid of scientific and computer technology a time is recreated when a two-tonne predatory fish came on land to hunt, and four-metre sea scorpions sliced sushi in the shallows, and when just one species of lumbering reptile represented eighty per cent of all life."
Also The Big Dinosaur Box. 4-disc. £8.48
"Presented by Kenneth Branagh this box set collects together the ground-breaking BBC documentaries that brought the prehistoric world to life. Includes: Walking With Dinosaurs, The Balled Of Big Al, Land Of The Giant Dinosaurs and Search For The Giant Claw. "
