TV and film both attract me equally. In both, you do search for a role that would be enjoyable to do, that has a great storyline and then, secondly, you look at the cast and the crew - are they respectable? How I look at it is my character - has the character got enough substance? It can't just be a one faced character, which is there to fill a gap. He has to have a purpose, so if it ticks all of those boxes then generally it's a good choice.

I think a lot of that is what helped me develop my character. I wouldn't say it was Method, but it was definitely a little more in depth than I've done before in terms of acting. With the other kids, we all were such good friends by the time we started shooting. Because of that, it allowed us to trust each other more to push the dynamics of the relationship to places which you might not be able to had you not trusted that person.

I still get star-struck by people like Harrison Ford, but I think it's become more natural and more a part of my life. You have to be professional and keep a straight face. You can squeal behind their backs.

I play a lot of strategy games and team and reactionary games. So it's a different sort of skill that you're practicing.

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.

For me, with any character, there are different ways that you approach understanding him, and in this film in particular, because I had the novel to refer to. It's always really helpful to have all of that information and all of those hundreds more words which give you an idea into the background and your character and all.
