An awful lot of filmmaking and playmaking is taken over by marketers and publicists, who set about to tell people what to think. And people feel safer that way. But it's not safe, and the whole wonderful thing that cinema and filmmakers can contribute is to go into the not-safe land of real life.

Integrity is so perishable in the summer months of success.

A deeper truth the camera can see can be more surprising than even the director imagined it could be. That's a wonderful thing that grows and happens in films.

What I didn't understand was that the personal and the political go together. I felt at the time I had to sacrifice my children's present for their future. It seemed an either/or. I didn't realise that by being with one's own children I would have had a better understanding of the ones who are not my own. I was thinking of them but I didn't spend the time that they needed from me. It's a tribute to them that they came out so well.

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.

On one occasion, Daniel Day-Lewis, Jeremy Irons and myself were due to appear at the Sarajevo film festival and were turned off a UN plane on orders from Geneva. We had to get local journalists to transport the films in for us. I tell you this only to demonstrate that festivals can be a lifeline. But, after all the difficulties I'd had in getting there, in 1996 I found myself being flown in on a four-seater RAF plane as an official guest, endorsed by the British Embassy. Ironically, the film I was to present was Mission: Impossible.
