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

I tend to get starstruck with sports people. I was on a chat show with retired Scottish footballer Denis Law and I just lost it and couldn't talk to him.

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 saw a ghost when I was staying at Dartington Hall in Devon in the 1960s. I think there are many different kinds of entities, some are scary and some aren't, it depends on the state of mind you're in when you are confronted. I found that quite scary because it appeared when I was asleep, so it was quite a shock, but the other ones I've encountered, I didn't find scary. I have a lot more understanding of them.

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.

I don't live in London - I'm based in Norfolk and have a place in Scotland.

If you travel to the continent you never have any problems overtaking, this is the only country I know where the outside lane is congested and the two inner lanes are empty. It drives me crazy. I'm ashamed that is so typically British.
