Making the films is never easy, but actually that aspect of trying to make a better film or to keep the standard high is something that comes organically.

The truth is, it's very hard looking back... we look at holocaust now with such knowledge and such a sense of the horror of what it was, that it's hard to believe even now that in 1930s and 1940s, before something like this had happened, that it could be impossible to imagine the extent of this horror.

I'm interested in making films of all sizes. During this time I've made a film called 'The Boy in the Striped Pajamas', which is a modest-sized film. I was involved in 'I Am Legend' and 'Yes, Man', but 'Potter' is unique. There'll never be anything like 'Potter' again.

The films you're making have to be faithful to the material.

It might sound odd, but I want to thank Michael Bay because hes been saying how important it is to show 3D with the right luminescence. And thats very important for this film, a lot of which was shot at night or with very low illumination.

I look forward to having the time and the opportunity to take on new challenges, but I'm also aware that I've loved every minute of the 'Potter 'experience: to make films for an enthusiastic audience and work with great material.

I like stories that begin with characters. I like to be engaged and moved by the characters in the story. I want to be moved. I want to leave the cinema and think about what I've seen. My sensibility is quite eclectic and it doesn't matter if they are small or large films, I just want to make good films.

I love books. I read voraciously, and I happened to have been fortunate to have been in the right place at the right time.

I got a few things, because I think the props are so beautiful as much as anything else. The detail of the work is something that one has no idea of.

All we try and do is make the best films we can. If you do that then hopefully the audiences will come, and they have. Everything else is gravy.
