I used to joke I was a point-and-click actor. My whole process has been about trusting your instincts and hitting your mark.

I'm not clumsy; just accident prone.

I absolutely don't relate to being beaten down my whole life - I had amazing opportunities at a young age - but there is still in many, many people's minds the notion that I'll never be able to escape Harry Potter.

And the people I'm best friends with on the films are not generally the actors.

I pretty much left full-time, formal education when I was 11. So that was when I was taken out of the school system... I think the longest stretch I would go back for was a term and a half when I was about 14.

Everyone on the set has a mobile phone, and I found by pushing a few buttons, they could be programmed into different languages. I fixed Robbie's Coltrane to speak in Turkish.

I think that the process of making a film is an underrated factor in how that film turns out.
