London: Oscar-winning actress Helen Mirren has dismissed the notion that she is an authority figure. The British actress said she often regrets of not being bold enough to be a rebel in school, reported a website.

"I was too much of a scared cat to be a real full-out rebel. I think it's absolutely shameful that I was never expelled from school. I see that as a blot. "(I never got close), too frightened to be naughty or perhaps too clever being naughty! Maybe I was too sneaky and they never found me out," she said.

Nirren, 67, has joined the roster of esteemed Hollywood stars who have lent their voices to a Pixar animation. "It's fantastic to be a part of the library of what I think are going to be great classics that people are going to be watching in 50 or 100 years' time."
