With Once Upon a Forest, Luc Jacquet 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…Only cinema can offer this unique voyage into a completely untamed universe, a world of perfect balance in which each living thing – from the smallest to the largest – plays an essential role. The film will deliver a complete sensory immersion in the primaeval splendor of one of nature’s richest mysteries, inviting the audience to enter, discover and marvel at a universe of untold treasures while joining its voice to the ever-growing awareness of the need to preserve our world.”
Unfortunately the movie Once Upon a Forest is not yet available on HBO Max.
