Olivia Wilde: Olivia Jane Cockburn

The 'Tron: Legacy' actress picked her own stage name and she took inspiration from legendary Irish playwright and poet Oscar Wilde.

She told The Observer: "At the time, I was doing 'The Importance of Being Earnest' - I was playing Gwendolyn , and I was so in love with it. Oscar Wilde is someone who I respect for so many reasons - a revolutionary, a comedian and a profound thinker."
