520 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. 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. The extraordinary detail and richness of the cinematography in This Changes Everything provides an epic canvas for this exploration of the greatest challenge of our time. Unlike many films about the climate crisis, this is not a film that tries to scare the audience into action: it aims to empower. Provocative, compelling, and accessible to even the most climate-fatigued viewers, This Changes Everything will leave you refreshed and inspired, reflecting on the ties between us, the kind of lives we really want, and why the climate crisis is at the centre of it all. Will this film change everything? Absolutely not. But you could, by answering its call to action.
