Movie star Keira Knightley finds movie premieres terrifying experiences because she is too shy to cope with the high levels of attention she receives at them.

Normally an open and confident character, the Pride And Prejudice actress dreads having crowds of people gawping at her.

Knightley, 20, says, "I'm just not good at premieres. I literally have to be dragged to them - they're absolutely terrifying.

"I have the car icy-cold because I break out in a sweat. I become soaked. But I have to go. They're sort of integral to my job.

"I don't know why I react that way."
