CANNES:

After years of failing to persuade the world’s most powerful politicians to take it seriously, former US vice president Al Gore on May 20 took his personal crusade against global warming to Cannes.

An Inconvienent Truth is a documentary of Gore’s slick one-man “travelling global warming show” which he has taken to some 1,000 schools and conferences around the US. Gore hopes the 98-minute film directed by David Guggenheim will inspire action among those who have so far failed to grasp what he calls “the biggest moral challenge facing our global civilisation”.
