Since I was a kid I've had an absolute obsession with particular kinds of American music. Mississippi Delta blues of the Thirties Chicago blues of the Fifties West Coast music of the mid-Sixties - but I'd never really touched on dark Americana.

For me great music doesn't just have to fall into one category or one genre and I love appreciating all kinds of music.

You know the BBC had not been particularly generous in its deliverance of blues and esoteric kinds of music.

There is two kinds of music the good and the bad. I play the good kind.

I like all kinds of music. I listen to Abigail Washburn the Punch Brothers and Marc Johnson the great clawhammer player. I also listen a lot to Sirius Radio there's a lot of bluegrass there.

Coming Home had been made before and Apocalypse Now and Deer Hunter different kinds of movies.

I am so happy because I want more people to like martial arts movie not just martial arts audience. Even martial arts can be used in comedy in drama in horror movies in different kinds of movies.

If you're not a real chameleon of an actor and if you're not one of those guys who can really shape-change themselves all the time one of the ways to keep pushing yourself and keep changing is to be in different kinds of movies.

I think people like to see the lives of artists that are legends. They always go through the dark periods and I think just as humans we like to see that and them coming out of it. I love those kinds of movies.
