Natural History Unit Silver Jubilee
Introduced by Derek Jones
To mark 25 years of wildlife film-making, the Natural History Unit shifts the focus from its animal stars to the people who bring the programmes to our screens - writers, presenters, producers and cameramen.
From a special exhibition commemorating the occasion familiar faces appear alongside the dedicated specialists whose skill and enthusiasm capture their wildlife prey on celluloid.
In the first of four programmes Derek Jones talks to Johnny Morris, Michaela Denis, and David Shepherd. With extracts from some of their films they recount the pleasures and problems, the humour and the pathos of those years on the track of wildlife.

Dr Bronowski tells the story of the men and ideas that gave concrete expression to the invisible, intangible structure that lies beneath all matter. The quiet of Niels Bohr's garden the clamour of great reactors and the silence of a Vienna cemetery are stopping points on the journey that ends at a neutron star, deep in space.
