If I can make a career for myself after Harry Potter, and it goes well, and is varied and with longevity, then that puts to bed the 'child actors argument'.

The real challenge of acting for me, I suppose, is just getting to know a character very, very well and just applying what I know about them to every single scene. That's what it can be broken down to.

A hero is also someone who, in their day to day interactions with the world, despite all the pain, uncertainty and doubt that can plague us, is resiliently and unashamedly themselves. If you can wake up every day and be emotionally open and honest regardless of what you get back from the world then you can be the hero of your own story. Each and every person who can say that despite life’s various buffetings that they are proud to be the person they are is a hero.

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.

I think of myself as being Jewish and Irish, despite the fact that I'm English.

I think it's kind of great, to be honest. I'll never do another film [like Swiss Army Man] where I get to talk about those things, so I might as well enjoy it while I can.

My favorite phrase, that a friend of mine who worked on the Potter films and was a lot older than me would use in front of me, and I picked up from him many great phrases - the English have a lot of great idioms for sweating. I don't know why that is. But that's what we do. I feel like it's particularly our country; probably everywhere has a lot of idioms for sweating. He always said, "I'm sweating like a glassblower's asshole," which I always found an incredibly strange and yet vivid image.
