Directed by Avi Lewis and produced in conjunction with Lewis' partner Naomi Klein's bestselling book of the same name, This Changes Everything is an urgent dispatch on climate change that eschews the abstract and rhetorical in favour of the personal and immediate. With Klein serving as narrator and guide, the film explores how our violent disregard for our planet has endangered both it and ourselves — and how resisting this abuse and opposing the forces that propagate it can have a profound — even revolutionary — impact upon the makeup of our society.
