I did listen to 1920s jazz or Al Johnson and a lot of early singers coming out of England. I would branch out a little bit to get a sense of the world that he might be coming into, in the '30s when jazz was changing.

I've got to give my brother a lot of credit because he's always introduced me to a lot of things and those films spiked an interest of, "Wow, this is an incredible world, how do you be a part of that?" That definitely helped me through my school years of doing theater.

I never went to stage school or anything like that. It was always plays, productions at school and things like that. The thing for me with acting was it was the only thing I could fully concentrate on. I loved playing sports. I didn't really love studying.

If you can have a show that has quite strong morals and cover important themes but be able to put them out to a broad audience, that's an interesting thing.

I'm a big fan of British cinema; I think we make some unbelievably brilliant films, but they can quite often have a dark feel.

I want to be 82 and doing movies with Paolo Sorrentino where people are like, "This is gold."

I want to go to the extremes and transformation is something I'm fascinated by. At the same time, you can transform but you can only really put what you've got inside you into somebody, so there's always going to be a degree of you inhabiting any role.
