In an interview with Weekend Magazine, the actress recalled having a breakdown on stage while appearing in a Paris theatre production, an incident which made her feel like she wanted "to die".
"I had suddenly developed stage fright and lost all my self-confidence on stage. In my last show, in Paris, my mind kept going blank on stage. I just wanted to die each time," the former Bond girl remembered.
However, Green - who will appear alongside her Casino Royale co-star Daniel Craig in the upcoming Starz series Camelot - went on to say that she prefers working on TV and film as she finds it easier to cope with the pressure.
"Working on Camelot was a lot easier, because with TV and films you can keep going back until you get it right," she explained. "There are some big crowd scenes in Camelot, and I did wonder if performing in front of them would be like going on stage, and I'd dry up, but luckily it all went well."
Green previously revealed that she suffers from crippling shyness and feels like passing out when put in the spotlight.
She has described the process of auditioning for film roles as "brutal" and admitted that she often "freaks out" in front of casting directors.
