The only thing is worrying about sleeping. If I have to be up early I worry about being able to get to sleep.

My very first professional job was with a theatre company in 1965 and the first job they gave me was literally shovelling sh*t. I was an assistant stage manager and they told me to clear out the prop store. I opened it up and no-one had been in there for 25 years and it was inches deep in rat sh*t. So before I could get anywhere I had to clear it up. I thought, 'All these years of training, the best drama school in the world, and this is what I'm doing.'

I worked with Judi Dench in Cranford. She's not at all starry, she's very easy and funny to be around, but I had such an enormous respect and regard for her before I met her that I was quite starstruck.

I can be very stubborn. I'm very opinionated and if people cross me at work - if people who don't know about the job try telling me what to do - I become very stubborn and really rather unpleasant.

I like watching DVDs, flying my plane, walking and going to my place in Scotland. I like yoga. It takes me a while to unwind, the subconscious parts of my mind take a while to catch up with the rest of me.

If someone opens a glorious Scotch or a bottle of wine, it's no more than a whimsy, but after nearly 40 years I'm used to it. I don't find it difficult not being drunk when other people are, but I get uncomfortable because they're uncomfortable with where I am.

There have been two [career highlights]. Waking up in New York to hear I'd been nominated for Best Actor for a Tony Award on Broadway, for An Ideal Husband. The other one was waking up the morning after the opening night of A Man For All Seasons and reading the reviews.
