Is the end result how you imagined it to be when you were writing the script?

It is extraordinary. I said to Amber last night that it is as good as I could ever have imagined it to be. It's due very much to Amber's efforts as the director, but I think if it weren't for the fact that we have got the most extraordinary cast, it just wouldn't work. I can't even begin to describe to you how pleased I am with the cast.

They're all so amazing. Patterson as Nigel is just incredible. What a voice - the guy has just got the most amazing voice. Emma and Joe and Anthony are doing everything we could possibly have hoped with the ghosts, but of course Rory and Jasmine are just perfect [too].

I just feel like, 'Maybe this happens all the time,' but I don't think so. I think if we'd gotten any other grouping it wouldn't have worked this well, so I think we really were fortunate in the way that this came together. They seemed to be having a really good time.
