Film links with green campaign

The film, which is Certificate 12A and starts at 7.30pm, will be followed by a webcast debate and has been dubbed as high profile as Al Gore's Oscar-winning "An Inconvenient Truth" climate change documentary.

It has been described as a moralistic call to arms set in 2055 in which Oscar-nominated actor Pete Postlethwaite sorrowfully trawls through real-life footage of climate-changing events in 2008 and laments that nothing was done.

The Age of Stupid climate campaign is encouraging interested groups to take part in the free exclusive webcast with climate change journalist – George Monbiot, Franny Armstrong (director of the film) and Dr Richard Betts, head of climate impacts at the MET office, live from the Royal Society of the Arts.

Directly after screenings finish across the width and breadth of the UK at 9pm, the organisers will go live from London with an interactive web panel beaming directly to anyone holding an event, including the Universal Hall. The panel will take live questions from audiences.
