I simply couldn’t conceive of how devastating it would be not to be able to hear my children’s voices. Not to be able to communicate with them, to hear them learn, grow, and express themselves verbally. How fortunate, how blessed I am. This overwhelmed me. I can talk to my children, I can respond to their needs and comfort them when they tell me they are unwell. I can tell them stories and hear them tell theirs.

Playing Juliet in Heavenly Creatures changed my life, and the role of Clementine in Eternal Sunshine of the Spotless Mind opened many new doors creatively.

There's more to life than cheek bones.

In films I might look glamorous, but I've been in hair and make-up for two hours.

With The Reader, I'd just be shattered at the end of every day really. I wouldn't really want to talk. We kept saying, because we were in Berlin: "If we get back at a decent hour, let's go and have a glass of wine." We'd always think it would be a great idea, but then get to the end of the day and then go [acts drowsy and blabs]. It was very difficult for everybody.

I wanted to play incredibly challenging, multifaceted characters. Because we are all a puzzle.

It's my chance to challenge myself to the fullest, which is one of the great joys about my job... I love it when a character requires me to look less than my red-carpet best. It's more fun playing a character that requires you to look like dog s - t.
