Clare would like That All There Is? by Peggy Lee to be played at her funeral.
Clare's biggest regret in life is that she has not raised a child.
Clare: I always think there is something indecent about acting at eight o'clock in the morning.
Clare: (On borrowing jewellery for the Tony Awards) I remember Harry Winston, the famous jewellers, ringing all of us women up who were nominated, and saying, 'would you like to loan some jewels?' and I said no! And they said 'why?' And I said, because knowing me, I'd just drop the diamond and ruby earrings down the toilet.
Clare: (On winning awards) You feel almost unfairly blessed because to get a reward, a prize, for something you love doing so much, seems to be ridiculous.
Clare: (On what she does with her three Olivier Awards) I balance one on my head and use the other two as dumb bells. They're very heavy, so they're great for the biceps.
Clare: (On her career) I can't say I had a 'big break' as it was a more of a steady thing, which I think is much better than being flavour of the month.
Clare: (Her definition of happiness) Sitting in total silence with a soulmate by Branwen's Grave on the river Alaw on Anglesey, watching the sun set.
