I feel there's so much still to learn about acting. But there is some magic in the capturing of performance and in the process of editing a performance. The psychology of human beings and what's coming through the face... that fascinates me.

It's thrilling to have the opportunity to work in different areas, whether it's on a project that has all the resources behind it like Harry Potter or James Bond and then to go somewhere there's very few resources.

I think I feel more like you're an actor for hire and you take the jobs you want to take, obviously, and some pay well and some don't pay well at all but you go on a gut feeling and it's all a big adventure.

So much of movie acting is in the lighting. And in loving your characters. I try to know them, and with that intimacy comes love. And now, I love Voldemort.

I went out to Mount Kilimanjaro, which I thought was very beautiful, but there were a lot of people there.

News reports can overwhelm us. We can be appalled, we can sympathise. But what is hard to grasp is the sense that, at this moment, people are working, organising - not just at an executive level, but on the floor, in the warehouse. A man is packing a box of oral rehydration tablets; maternity kits are being prepared; education kits are being packed. And somewhere, tomorrow, those boxes will be unpacked and a child with life-threatening diarrhoea will be saved, a baby will be born in more hygienic circumstances, a girl will receive her first exercise book and her first pencil.

It [the scene] can be something given to you and you go, "Ah this is a good idea, I can work with this." Sometimes it cuts right across your instinct and that's when I might resist. Even if the director might be insistent, I think it's very important to say, "Look, I'm not feeling this. I'll try to make it work but I got to let you know."
