In a rare move, the Cannes Film Festival has chosen a documentary as its Closing Night Film next month. From Luc Jacquet, director of the Oscar-winning March Of The Penguins, Ice And The Sky marks a return to the Antarctic of sorts. The subject of the film is glaciologist Claude Lorius who in 1957 began his study of Antarctic ice. In 1965, he was the first to be concerned by global warming and its consequences for the planet. Today, at age 82, he continues to look at the future with hope.

Jacquet’s body of work includes environmental and nature issues from Penguins to The Fox And The Child and Once Upon A Forest. He calls Ice And The Sky‘s inclusion in Cannes “a huge opportunity… Showing this film in the world’s largest film festival is contributing to this huge challenge facing humanity as quickly as possible to secure its future and the future of the planet. My language is cinema. In different times, I would have made other films. But I make fierce cinema, political cinema, cinema that has no choice.”

Pathé is releasing in France and Wild Bunch has international sales on Ice And The Sky. The film screens May 24, following the prize ceremony.
