Eco-friendly actor Edward Norton is calling on Hollywood studios to become more green friendly. He admits that most of the studios are already setting a good example, but he wants Hollywood to do more.
He says, "I think the studios are doing their part. Not just because it's the right thing to do, but also because it's cost effective. They need to look at the way films get made. There's a lot of waste in the way we make films."
Norton will also be narrating an environmental series called "Strange Days" on Planet Earth, which will airs on PBS tonight!
