Just in case anyone hasn't heard about it yet, this sounds like a really interesting film. The Age of Stupid had it's premiere last week and went on general release from yesterday, 20 March. I watched the documentary of the making of the film online and thought it was very interesting. Here's the blurb about it:
The Age of Stupid is the new movie from Director Franny Armstrong (McLibel) and producer John Battsek (One Day In September). Pete Postlethwaite stars as a man living alone in the devastated future world of 2055, looking at old footage from 2008 and asking: why didn’t we stop climate change when we had the chance? It will be released in UK cinemas on 20 March 2009, followed by other countries.
