I have this horrific thing where I'm really bad with names and faces. I have an appalling memory. Someone will come up to me in the street and go, 'Eddie!', and I'll try and give myself time by going into overdrive, 'Hey, hi! Nice to see you!' and start a whole conversation because I can't distinguish between who I know and who I don't.

I feel like J.K. Rowling's world is one that is owned by everyone in some ways. People have grown up with it and have such a sense of that universe that there's something kind of wonderful seeing everyone get involved.

Making a film or doing a play are completely different experiences and entirely fulfilling, but completely unique. I also think one complements the other. People often say that theater is about flexing your muscles, and is actually real acting, whereas I sort of disagree.

As an actor there's a lot of scrutiny and, even when you've had success, it becomes about sustaining that success. A friend of mine described it as a peakless mountain. Even for Robert De Niro there's Al Pacino and for Pacino there's De Niro.

My first film, 'Like Minds,' was with Toni Colette, who was extraordinary. I mean it was basically a mini-masterclass for acting on film at a time when all you could probably see were my eyebrows bouncing up and down on screen.

I walk around talking to myself in accents. Usually people look at me like I'm a complete fruit loop.
