The book This Changes Everything — Naomi Klein’s opus on how climate change could be our greatest opportunity to reinvent the world before we destroy it — is now becoming the movie This Changes Everything. Directed by Klein’s husband, filmmaker Avi Lewis, it will soon make its way into theaters.

From the movie’s website:

Filmed over 211 shoot days in nine countries and five continents over four years, This Changes Everything is an epic attempt to re-imagine the vast challenge of climate change.

Directed by Avi Lewis, and inspired by Naomi Klein’s international non-fiction bestseller This Changes Everything, the film presents seven powerful portraits of communities on the front lines, from Montana’s Powder River Basin to the Alberta Tar Sands, from the coast of South India to Beijing and beyond.

Interwoven with these stories of struggle is Klein’s narration, connecting the carbon in the air with the economic system that put it there. Throughout the film, Klein builds to her most controversial and exciting idea: that we can seize the existential crisis of climate change to transform our failed economic system into something radically better.

Let’s hope so.

This Changes Everything will premiere at the Toronto International Film Festival on Sept. 13, and will start showing in theaters in the U.S. and become available on iTunes on Oct. 20.
