Beverly and Dereck Joubert are wildlife documentary producers. This husband and wife team lived in northern Botswana and captured on film the family relationships of the last free-roaming elephants left in Africa. Their 1994 film "Reflections on Elephants," contained ground-breaking footage of lions attacking an elephant calf. Previously, such attacks were thought to be only mythical. Their book "Hunting With the Moon: The Lions of Savuti" was published last year by Random House.
TV Critic David Bianculli previews a two-part documentary titled "The Private Life of Plants." It will be featured on cable TV's TBS network tonight and tomorrow night. Bianculli says its the best documentary he's seen this year.
