I think there's an initial shedding of the skin of a character when you've played them for so long, almost like a snake losing its skin. But when a job is done, I kind of walk away from it because I know that I need to prep for whatever else I'm going onto - I need to get back to being myself, which... Who knows exactly who that is, with all the talking voices in my head. You know, back to being a bit of a blank slate again. It becomes a necessity as an actor - at least for the way that I act.
