A friend told me that teenage girls are always looking for someone to pin their dreams on. That doesn't make it any less weird though.

The truth is - I found myself doing these huge action-adventure movies, and um, and which are cool man. And I really love doing them. And thankfully I haven't had too much dialogue, because if I had I would have really made a mess of it. You know what I mean?

When everyone around you is doing all this incredible pirate acting and you're having to sort of play the straight guy and move the story forward, you kind of want to be doing some of that pirate ripping it up stuff, but in truth, to be a part of that project is what I love.

I wondered how they would top the Pirates and skeletons and moonlight, because that's a pretty cool concept.

Although it is a fantasy film, it's as real as it can be. You have to imagine that an audience will buy their ticket to a cinema and get on a first-class flight and journey to Middle Earth.

My experience of singing, as an actor, was that there's a different creative feeling of freedom. The acting thing is a bit more defined and cerebral. I can see why people would want to cross over. If you have so much freedom on stage then perhaps you want to be confined a bit, and vice versa.

I need to keep reinventing myself.
