Actor Matt Damon has lashed out at U.S. Republican vice presidential candidate Sarah Palin - insisting she's been chosen for "political purposes".

Damon fears Palin's running-mate John McCain won't survive a full four-year-term as president at age 72, and claims the Alaskan governor taking over would be disastrous.

He says, "I think there's a really good chance Sarah Palin could become president, and I think that's a really scary thing. It's like a really bad Disney movie, the hockey mom, you know, 'Oh, I'm just a hockey mom from Alaska'... and she's facing down (former Russian) President (Vladimir) Putin... It's totally absurd... It's a really terrifying possibility."

And Damon takes issue with Palin's take on the creation: "I need to know if she thinks dinosaurs were here (on earth) 4,000 years ago, I really do - because she's gonna have the nuclear codes." (c) WENN
