Helen Mirren, on the perils of youth: “Your twenties are torture, really, because you don’t know what you are going to be or whether it’s all going to work out, and you are supposedly an adult but you haven’t really learnt anything. You’re always looking for your own place in the world, but you’re insecure – you think you’re wonderful one minute and you think you’re a disaster the next. I think your thirties are a wonderful time.”
