Mark Ruffalo would like to see an eco Hulk movie

Mark Ruffalo has revealed that he'd like to see a Hulk solo movie with an environmental slant.

During a talk at the Sundance Film Festival, the star talked openly about his movie debuting at the festival - Infinitely Polar Bear - before going on to tackle the topics of fracking, sustainability, practical and cost-effective environmental change and then finally a brief aside over a solo Hulk movie.

Noting that he'd like to use his art and fame to spread a more eco-friendly message, he praised the positive potential in using his stardom as a platform to spread the word.

"As artists we have an ability to reach a lot of people in a deep way, and we have a responsibility," he said. "What we have to do as storytellers is to take science and make it relatable.

"I think we have to tell the story of the positive and what we're going to try to do. Give them alternatives but don't make it a polemic," he intoned.

When prompted on how he could apply that kind of message to bigger studio movies and blockbusters like The Avengers , he was equally as thoughtful.

"I think that's the way to go, and it's a trend that'll start to develop. As a culture, when we latch onto a fad, we're actually working something out in the creative subconscious. The fact that all these doomsday and end-of-times movies are coming out is because we're actually working that out in the culture."

"I'm in The Avengers , but if you took my screentime it would come to about ten minutes, along with the 12 other people I'm sharing the screen with, so my input's kind of limited on that. But if we get to a standalone Hulk movie, I'll have a much better chance to do that. I'm just learning now how to find my voice and bring it into the studio world."

So if/when the inevitable Hulk movie comes along, we could be seeing an even more green version of everyone's favourite emerald rage monster.
