The Avatar-director has teamed up with producer Jerry Weintraub and a cadre of celebrity correspondents to create Years of Living Dangerously – an eight-part documentary series on the human impact of global warming, to air on Showtime in 2014.

"Everybody thinks that this is about melting glaciers and polar bears," says Cameron about half-way through the just-released trailer. "I think it's a big mistake. This is 100-percent a people story."

Joining Cameron in the telling of that story is Harrison Ford, Jessica Alba, Matt Damon, Olivia Munn, Michael C. Hall, Mark Bittman, Arnold Schwarzennegar and more! Which – hey, if it takes a bunch of celebrities in helicopters and an incredulous Lesley Stall asking "this is a lake??" to make television viewers care about climate change, consider us onboard.

Years of Living Dangerously will premiere April of next year and run for 8 episodes.
