I don't really know what the dream role would be. That's a hard question to answer. You never really know, until you're immersed into something, how passionate you feel for it and how it unravels.
It's funny because if you ever ask anyone in England to try and do a Beatles accent, no one knows what they really sound like. If you ask anyone in America, they would try and give it a go. English people just know their songs.
