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.

We’re damn lucky to have our bodies, these strange, multi-functional machines, that let us leave our legacy on the planet.

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

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.

I don't want to know what they think of me - there's always going to be someone who won't like it and that'll just upset me. So, if I'm happy with it, it just matters if I've done my little vision.

It calmed me down to see that most of the time no-one gets the scene on the first take.
