Keira Knightley: "I am Completely Uneducated"

Keira Knightley says she is "completely uneducated" after forsaking university in favor of a career in Hollywood.

The 'Edge of Love' actress says she now battles to prove to herself -- and those around her -- that she has brains.

She says, "I am completely uneducated. Not going to university did give me an incredible driving force because it leaves you with a slight chip on your shoulder.

"It makes me feel I am going to read absolutely everything so I can prove that I am not stupid."

Keira -- who was diagnosed with dyslexia aged six -- dropped out of school at 17, before taking her A-levels, after landing her breakthrough role as Lara in a television adaptation of Doctor Zhivago.

She shot to fame in the 2002 film Bend It Like Beckham and went on to play Guinevere in King Arthur, Cecilia Tallis in Atonement and Dylan Thomas's lover Vera Phillips in The Edge of Love, as well as the blockbuster Pirates of the Caribbean movies. She recently signed up to play Cordelia in a film version of King Lear.

Her next ambition is to appear on stage, but she will not be taking a starry role in the West End.

She added to Tatler magazine, "I can't quite handle the idea of 'Screen Actress in Big West End Hit' and all that. I would prefer to do something smaller.

"Everything scares me. The idea of doing theater scares me in an exciting way but doing any part always terrifies me... It boils down to a fear of standing there in a wig and a dress and suddenly thinking, 'I feel like an idiot.' You must not let your imagination see the absurdity of it and cause your performance to die."
