I was fortunate to see a Preview Sreening of this film, described by The Guardian as: 'The first successful dramatisation of Climate Change to hit the big screen'. Oscar-nominated 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? From an archive buliding containing some of the world's most precious art treasures, he shows us documentary footage of six contemporary characters - ranging from an 80 year old french mountain guide witnessing the shrinking of his beloved Alpine glaciers, to the belligerant head of an airline aspiring to be India's answer to Easy Jet. There are also stunning otherworldy animation scenes showing the devastated planet in 2055, and Monty Python style cartoon sequences delivering sobering stats on consumerism. All set to a cracking soundtrack from the likes of Depeche Mode and Radiohead. The science behind the film has been meticulously researched, but it's not all doom and gloom. The movie's real strength lies in its humour, and its hope. For it aims to turn every one of us into a Climate Change activist. There's still time to avert a global crisis of biblical proportions, but only if we act NOW.
