It seems to me that the years between eighteen and twenty-eight are the hardest, psychologically. It’s then you realize this is make or break, you no longer have the excuse of youth, and it is time to become an adult – but you are not ready.

In Shakespeare's day it was women who were being burned at the stake as witches... not men. The men were thought of as alchemists. But women doing the same thing would be a witch and would be burned.

I do think it's well over-time to have a female Doctor Who. I think a gay, black female Doctor Who would be the best of all.

There's a heartbeat in any country that carries on regardless - at least in Europe. That's what worries me about America, because I'm not sure what that heartbeat is - unless it's the heartbeat of someone who's just arrived, who just ran over the border two weeks ago.

It's so hard when you're young to look at older people and understand that they have been where you are. It's the weirdest thing. You just can't get your head around that, can you? You can't get your head around the fact that someone who is 60 was once 16, if you're 16. But the fact is they have been, and they remember it.

A war film can be propaganda and they're very valuable as propaganda, as we realized in Britain in the Second World War. Film as propaganda is a very valuable tool. It can also demonize, which is the dangerous side of a war film as propaganda. But there are war films that are not propaganda. It's just saying 'This is what it's like.' For 99 percent of us we don't know what it's like. We have no idea. So to reveal that to the audience is powerful.

When I was doing Shakespeare and I had spent a lot of time and effort in trying to become a great Shakespearean actress. That was how I started my career, was in the theater doing Shakespeare. And my ambition was to be a great classical actress. That was what I wanted more than anything. So, I really pursued that in the first four years of my career. And it was an uphill struggle. It really was. Shakespeare's difficult and Shakespeare in a big theater is even more difficult. So, anyway, it was a struggle for me.
