Movie star Pierce Brosnan has launched a scathing attack on US President George W Bush, accusing him of ruining the environment and starting the Iraq war.

The James Bond actor and father-of-five is appalled at the leader's slow approach to discussing the world's climate and is not afraid to speak his mind about it.

He says, "I find it very difficult to have faith in this president. And that's coming from a man who has kids who have a future on this earth, looking at what he's done to the environment and this savage war that has started.

"I'm a member of society and I have every right to speak of my own perspective.

"But I don't know, I've already had backlash on the internet."
