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".
As above. Those interested in special effects techniques will appreciate the inclusion of a 50-minute "making of" documentary (which is also on the VHS). There's also an informative director's commentary, plus some behind-the-scenes picture sequences and additional graphics. The sound is vivid Dolby stereo and the picture is anamorphic 16:9 widescreen
Walking
With Dinosaurs - Ballad Of Big Al 
The programme contains two separate half-hour segments. The first is a biopic of Big Al, the allosaurus whose remarkably complete skeleton, found in Wyoming in 1991, allowed scientists to piece together an accurate picture of the creature's life.
The second programme is a "making of" documentary, showing how scientists analysed Al's bones and came up with a plausible series of adventures for him.
Walking
With Dinosaurs - Ballad Of Big Al 
As above. The creators of 'Walking With Dinosaurs' tell the story of the complete dinosaur fossil which was found in Wyoming in the USA. Research found that the fossil was one hundred and forty-five million years old. This programme recreates the life and times of that dinosaur.
