Mark Ruffalo aka the Incredible Hulk is the natural gas industry's worst nightmare: a serious committed activist who is determined to use his star power as a superhero in the hottest movie of the moment to draw attention the environmental and public health risks of fracking.

Every time I have some moment on a seashore or in the mountains or sometimes in a quiet forest I think this is why the environment has to be preserved.

I don't set goals. Like that's what I want to be doing however many years from now. I do what I love to do at the moment. If I wake up tomorrow and decide I want to dance that's what I'd do. Or design clothes.
