When somebody can't reveal what they're after - whether by word or by how the camera is set up, lighting, etcetera - it's like an electronic beep beep; it interferes very much with what we actors can do. And, after all, the director wants the actors to be bringing forth the best that they can, according to whatever vision he has.

The great writers like Chekhov know that tragedy and laughter are just a few steps from each other ... but it took me a long time as an actress to learn that. Actually Arthur Miller taught me in the Seventies. We were making a CBS TV drama of his play Playing for Time about Auschwitz but the characters were laughing. It was a big insight for me to realise that that was what's called gallows humour, in this case worse than the gallows, that humans need to laugh and make jokes in order to survive.

As a mother you have got to have a view for now and a view for the future.

How can there be democracy if the leadership in the United States and Britain don't uphold the values which my father's generation fought the Nazis, millions of people gave their lives against the Soviet Union's regime, didn't they? Because of what? Democracy. And what democracy meant. No torture, no camps, no detention forever or without trial, without charges. In solitary confinement. Those techniques which are not just alleged, they have actually been written about by the FBI. I don't think it's being far left - I hope that I'm wrong to consider that it's far left to uphold the rule of law.

There always comes a moment where all the departments in a film need to work together. And if a director, his first assistant director, and cinematographer have a very clear vision, then everybody does work together.

One of the joys of cinema is that, given the right circumstances, and the genius director, an incredibly wonderfully actor can become the embodiment of his character.
