I've basically grown up with Harry Potter, as so many kids my age have. It's kind of a part of my life.

My whole life I try to make into a comedy, so it would be nice to see that onscreen.

I was 12 and I remember every­thing. I mean, I had done two films before that. The first was actually with Amy Heckerling. It was so brilliant to work with her on my first film. Atonement was the third one I'd done, and I remember how it felt to arrive on set every day. I remember how it felt to get my wig off at the end of the day. I remember how hot it was.

The written word can be powerful and beautiful - but films transport us to another place in a way that even the most evocative words never can.

We've done a lot of films now about the IRA, we can move on from all that. I loved '71 because I think it showed a very honest trail and what it was actually like. It wasn't one-sided. I really respect ['71 director] Yann [Demange] for what he did. But we have done a lot of those things.

I've grown up with my parents' music tastes, listening to Fleetwood Mac and the Rolling Stones.

Learning is the most important thing, no mater how you do it, or where you do it, or who you do it with.
