The green premiere

At the premiere for The Age of Stupid, Pete Postlethwaite and his co-stars arrived in cars powered by cooking oil and stepped on to a green carpet.

It claims to the the world's greenest premiere, and the first to be solar powered.

The film itself is set in the year 2055, where Postlethwaite's character looks back at the impact of climate change and asks why we did not do more to stop it.
