After I had prostate cancer, I had something which was misdiagnosed which led to a load of back operations.

The moment the doctor said he wanted to do a biopsy, in my heart I thought I'd probably got it. But I also know a lot of people who have also had prostate cancer, so I had a reasonably good idea what to expect.

I guess we've had a very close relationship because I don't pretend to know about cinema and I think I do know a bit about theatre but he does, he respected that and so we really just had a collaboration which went completely like this.

Superstar was made so early in my career I had nothing to do with it at all. The first time I saw it was the opening screening.

'The Phantom of the Opera' is the biggest thing I've ever done, bigger even than 'Cats' which, in itself, I never thought we'd top.

You're the luckiest person in the entire world if you know what you really want to do, which I was lucky enough to know when I was very young. And you're the luckiest person in the world if you can then make a living out of it.
