Our oil-based society depends on non-renewable resources. It requires relentless probing into vast reaches of pristine land, sacrificing vital bioregions, and irreplaceable cultures. The possibility of catastrophic climate change is substantially increased by the 40 million barrels of oil burned every day by vehicles.

I have learned from my experiences in this industry that there is absolutely no way to control people's opinions on your performance in your movie. You go out there, promote your film and hope people like the work you did.

It's not just global warming, it's not just a loss of biodiversity, it's not just the pollution of our oceans and the clearing of our rainforests and all these complicated systems, The [11th Hour] movie talks about the world economy, it talks about politics, it talks about personal transformation and environmental consciousness that we need to have in this generation to implement a lot of these changes that need to occur.

The truth of the matter is this - I never look for films specifically, because ultimately if the fundamentals of the character and the script and the director aren't there, it makes it a moot point.

I'm a big history buff so to walk the streets...the ancient world like that was pretty astounding.

And now it's your turn - the time to answer the greatest challenge of our existence on this planet is now.
