My emotional investment started when I read the first scene of the actual drama [45 Years]. I can't explain it, there's no logic to it, but the notion of one's youth that somehow comes back but is gone, a man of my age connecting to that timing of life.

My now-wife - we got together in '81, we married a few years after - she's been very good in the past about going in the theater with me to see actresses I had known. But then, she's not an actress.

I never did anything about my stardom, it never meant anything to me.

This is something particular to actors, especially in plays, and in films, too - but in plays, it's like, don't get involved with anyone in the play.

I keep saying that backwards is all you can see. You can't see front. My wife says, "Stop, you're always in the past." She sees me sort of daydreaming.

I don't want to peak too early. The worry is that you never know until it's all over whether you peaked at all - and then you're finished and it's too late.

The film business is absurd. Stars don't last very long. It's much more interesting to be a proper actor.
