In terms of putting the cast together, no problems. You know, the only problem always is just price-point. Our ambitions as we get older, all of us, is to try and do more.

So that is new in terms of where I've seen the shifts. Otherwise, it's all about taste and taste just keeps going round and round and round.

There's always that possibility. But, it would take a hell of a lot of work. Because unlike a movie where you just have to do a little ADR and then some mixing, we've actually got to bring the orchestra back because there is music, as you probably noticed, right the way through the film so you have to orchestrate all of that extra time.

For me, I can't tell you if the film is good or bad, all I can say is for me the film is way better than I had expectation of us being able to make. So for me that's the most important thing. Have we exceeded our dream in terms of what it could be?

My theory is, I don't know how long it's going to be five or ten years, there will be only two ways to see a movie and that will either be on your computer through your TV screen or in the cinema, end of story. There will be no DVD, that's it, simple.

The idea that the Tony committee and the New York theater community as a whole have embraced Billy Elliot is very, very exciting.

So, to me, it does shift, but it goes round. It just keeps going round and round and round. So if you have the longevity you have the belief and you have the resources to just keep at it you just ignore all that and just keep going where you're at.
