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.

Most films are rooted in a book or a comic strip, but I don't go out there saying I want to do adaptations.

Success is all about being able to extend love to people. The people I consider successful are so because of how they handle their responsibilities to other people, how they approach the future, people who have a full sense of the value of their life and what they want to do with it.

Education, awareness and prevention are the key, but stigmatisation and exclusion from family is what makes people suffer most

Being an actor means asking people to look at you. I guess I accept that. But it's a profession in which the job is to show another world and other people. You may access it through bits of yourself, and your imagination and experience, but actually, in the end, you're not playing yourself.

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.

I learned a lot about acting - watching not just myself but other actors and learning how to distinguish between two great takes. It's also about one's own taste in performance.
