After An Inconvenient Truth, this environmental documentary probably had the greatest impact on the public's opinion of global warming, and at a crucial moment in American (and world) history. The urgent message and solutions presented in The 11th Hour were made all the more alluring thanks to star producer and narrator Leonardo DiCaprio. "Essential viewing...an unnerving, surprisingly affective documentary" (Manohla Dargis, New York Times). "I agree with every word..." (Roger Ebert, Chicago Sun-Times).
