Sometimes I`m stressed and I`m sick of things and I need to forget about them for a while, so in Harry Potter you`re taken to this wonderful imaginary world where everything is so different. But also the main characters are completely real and modern so you can relate to them.

Drawing on the experience I have of now directing, to me, my one strength that I know is my ability to communicate with actors and therefore make characters really important.

It was this feeling the whole time like I shouldn't be here among all these stars and professionals. I was trying to keep my distance because I wanted to watch everyone. But they want you to feel at home and be part of it, and it became normal very quickly.

While I was in London it was completely upside-down. I got a whole new life and it was a challenge to keep in touch with my life in Ireland, but it was great fun. Now though, I've been back home since November and gradually all connections with my HP life have been fading.

One week I was in school and the next I'm at Leavesden Studios in Dumbledore's office reading scenes with Daniel Radcliffe. Weird. And terrifying for such a huge 'Harry Potter' fan

I've been back home since November and gradually all connections with my HP life have been fading. It’s gotten to the point where I feel like it was a dream because everything has gone back almost exactly to how it was before it all happened. It's possible to forget and it’s only when someone asks ‘when’s the movie coming out?’ that I remember 'oh yes, that'.

I think there are a lot of writers that can get away with not being gifted with words.
