I managed to stay grounded and when I wasn't working, I was hanging out with my friends so I was still able to be a kid and have that part of my life. I didn't let acting take over completely.

When you really want a role and you really want a character, you become quite close to the script and the project, and it is sad when it doesn't go your way. But I've found there's always another one, which will be as good if not better. You can't let your failures bring you down when you're an actor, because then you can't get up.

My theory. Music can fix anything. Anything.

In terms of my relationships with a lot of the adult characters, when I was working with Harrison, it wasn't like a verbal agreement, but we both understood that because there was this constant tension between our characters, we couldn't say "Cut" and start acting normal. We had to keep an essence of that relationship in our characters off screen which is really important.

The first time I met Harrison, I think, was at the very first read through of the script. As anyone would be, I was a bit nervous before meeting him. I mean, it's Han Solo, so it was quite crazy. But once you get to know him, he really is such an amazing person. He's such an amazing actor as well. As I said before, his presence really does get the best out of you as an actor.

It's kind of hard to enjoy the film when you are watching yourself the whole time. But you do get on with it and try and appreciate everything else about the movie. At least that's what I do. It depends on how fresh in my memory the whole experience is.

I think that a lot of the time I don't go for something in particular. I see what comes to me, I filter it out. I never really strive to play a particular character or do a particular genre of film. As long as it's a good script and a great range of people and my character is really interesting I can't see any reason not to do it.
