Written and directed by Luc Jacquet, Once Upon A Forest invites the spectator into a never-before-seen world of natural wonder and staggering beauty. For the first time, we will be able to watch a rain forest growing before our eyes. Drawing on a vast fund of research and knowledge, Once Upon A Forest will lead viewers on a journey into the depths of the tropical jungle…into the very heart of life on earth. For years, Luc Jacquet has spellbound audiences worldwide with his intimate yet spectacular stories of the natural world. His encounter with pioneering botanist and ecologist Francis Hallé was to give birth to this extraordinary exploration of the prehistoric rain forests, the great green lungs of our planet.
