Hot Docs Film Festival: Planetary

Witness Earth like never before. Through telescopic lenses positioned in deep space that are trained on the peaks of the Himalayas, the African savannas, the hyper-paced streets of Tokyo and the vastness of the cosmos themselves, this visually astonishing portrait of our planet is designed to humble the viewer. In an effort to grasp not only the fragility and beauty of this world, but the near-incalculable breadth of our impact on it, Planetary intellectually challenges us to reconsider our relationship with our home.
