When I have a good performance, I'm wrecked at the end of it. I feel completely empty, and tears are pouring down my face - I'm just gone.

When 'Jewel' was screened, old friends from school and university got back in touch. More than one of them told me that their partners hated Merrick so much they could not think of having me in the house. This kind of audience identification does not happen in any other medium.

Everybody wants a movie career. I found that pretty elusive. I did make a movie with Martin Sheen about a nuclear scientist who has a religious experience. I don't even know what it was called. I don't think it was ever released.

I have only met Prince Charles once, when he was very charming and easy to chat to. I have always had a soft spot for him, and I admire our constitutional monarchy, but Charles often comes across as eccentric, and he has a mixed press.
