"Lascaux cradle of man's art" is the first colour film to be shot in the Lascaux caves. Lasting 17 minutes, this documentary on the caves discovered in the Dordogne in 1940 reconstructs the circumstances of the discovery. Two little boys chasing a rabbit with their dog fall underground into the caves and discover that the walls are covered in animal forms. The film explains how these paintings are one of the most important discoveries of prehistoric remains. It was in 1946 that the American journalist William Chapman heard about the Lascaux caves. He made a report about it and thought of bringing the prehistoric paintings to the screen. He made the documentary in 1948 and, in 1950, the Antibes Festival revealed to Europe a film that had already astonished the United States.
