America's top green heartthrob Leonardo DiCaprio is bringing his much-anticipated environmental film, The 11th Hour, to the Cannes Film Festival for a special screening this Saturday. And although there's no way most of us are going to make it there for the event, we're pretty excited nonetheless.

DiCaprio's film features interviews with over 50 leading scientists, thinkers and leaders (such as David Suzuki and Stephen Hawking) -- discussing the state of the world and humanity. Sounds pretty heavy. The title refers to the last moment change is possible (right now) and shows how we got to this point and what we can do to save ourselves. We don't know too much else about it yet, but hopefully we'll be able to glean some interesting details before it officially hits theatres.

Until then you can visit the 11th Hour site and join the campaign to “Lighten Your Footprint”. And of course you can read all the interesting tidbits about greening efforts at Cannes. Am Pav (the American Pavillion) is being sponsored by The 11th Hour to keep its recycling program going strong. Al Gore’s An Inconvenient Truth sponsored it last year.
