My theory. Music can fix anything. Anything.

I like to keep my options very open and try not to focus on trying to get something. That's just how I'm playing it and it's worked so far.

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.

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.

Some advice to you guys, don't ever take keep your phone in your pocket whilst on a roller coaster.

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.

I think I can speak for a lot of people in that they would be pretty nervous about meeting Harrison Ford, and I was definitely one of those people.
