Ryan Reynolds is claustrophobic

London: Hollywood actor Ryan Reynolds has revealed that while shooting for his new film Buried, he had to face lifelong fear -- claustrophobia.

In the film, Reynolds stars as a trucker who is kidnapped in Iraq and buried alive, and he spent two weeks shooting in a prop coffin to finish the underground sequence.

Reynolds "emerged skinless", battered and bruised - and even with a small bald spot - after being locked in the coffin for hours.

Dailystar.co.uk reports Reynolds insists dealing with his anxiety was the worst part.

"Even elevators start to feel like a large sweater to me. Big spaces agree with me just fine," he said.
