Sienna Miller has morphed from a minor league actress to a minor league environmental crusader. Switching her allegiance from Jude Law to celebrity-studded Global Cool, she has just returned from India where, as an ambassador for the organisation, she was meeting A-list Bollywood stars and saving the world. Miller made a spoof film trailer with some of them in an attempt to raise awareness of climate change in India. They all posed as superheroes saving the planet by switching to low-energy light bulbs and sharing cars. It was shown on t.v. and 400 million people potentially saw it.
