I've known Emma Watson since she was 9, we've watched each other grow up, formed this sort of brother/sister bond, and suddenly I'm leaning in to kiss her. Well, it felt completely wrong... but, you know, you try to sink into the character and divorce yourself from it. We ended up laughing hysterically afterwards.

Walking into the great hall for the first time was absolutely incredible - all these effects with all the candles floating in the air, all lit and everything, food on the table, all the flambeaus were lit - it was just incredible, it was the most amazing thing I've ever seen in my life.

The most challenging scene for me was the spider scene, because I don't like spiders in real life. Even rubber ones I get really scared of.

Leave home? It's quite a scary thought. I'm not the most independent person and that's the result. When you're always surrounded by people it becomes quite normal.

So yes, I do want to try and keep things going if I can. I have a few things brewing And if it doesn't happen, I did buy an ice cream van a while ago. So I always have that to fall back on.

People recognize me, call me Ron, and ask me questions. It's really cool and weird as well.

I found out that you could audition by sending a picture of yourself and some information to Newsround.
