There have been many films about lions but never one like this. Previously you have only seen the lion during the day. But lions are nocturnal animals and daytime hunts are the exception rather than the rule. Now, from Savuti in the Chobe National Park in Botswana, comes a remarkable study of the secret life of the lion. For three-and-a-half years a team of researchers has followed lions throughout the night by the light of powerful searchlights. Using low-level film lights and extra-sensitive film and lenses, their researches have been recorded. Almost incredibly, the lions became quite used to the noise of the trucks and the lights. This has made possible a unique new view of the cruel and restless life of the lion at night.
